Components must be valid in order to be deployed. This page covers how to identify invalid components and view the validation errors associated with them, as well as how to resolve validation errors.
This section covers how to identify invalid project components and view the validation errors associated with invalid components.
During project design, it is expected to have validation errors until all project components are configured properly. For this reason, validation errors, which often resolve on their own while you configure a project, are hidden by default.
As project design progresses, to aid in identifying components that have validation errors, you can toggle on highlighting of invalid components. To highlight these components, in the top right of the design canvas, select the checkbox for Highlight Invalid Items:
This view can also be toggled on using the Invalid filter in the Components tab of the project pane to filter on invalid items.
When this display option is selected, the names of invalid components appear in italics and the color red on the design canvas and in the project pane. In addition, on the design canvas, blocks representing invalid project components are outlined with a red border:
In the project pane, invalid components that have an implicit error are shown with an error icon . The error icon does not display if the reason the component is invalid is because it contains other components with implicit errors. For example, a workflow may be invalid because it contains operations or other components that are invalid, or an operation may be invalid because it contains other components that are invalid, as shown below:
After the highlighting option is turned on, to display validation errors for components identified as implicitly invalid, click the error icon next to the component name. A message displays the validation errors for the component. For detailed information on what causes components to be invalid and how to resolve validation errors, see Validation Rules, next.
Certain validation rules must be followed for project components to be deployed to the Harmony cloud and for operations they are used within to be executed on Harmony agents. These rules ensure that all parts of a project are supported and expected by the agent. Validation rules for workflows and operations are covered on these pages:
The rules for other individual project components are detailed as follows.
Names Must Be Unique
Names of some types of project components must be unique for each type of component.
Depending on which component is invalid, the appropriate variation of this error message will be returned if this rule is not met:
[Operation / Connection / Activity / Transformation / Script / Email / Variable] names must be unique.
When creating a new project component from scratch, the field validation included within the component configuration screen will not allow you to provide the same name for multiple project components. However, you may receive this error message if, for example, you have imported a project that contains components with duplicate names.
If you receive one of these errors, check to make sure you have given a unique name to each project component and rename any duplicates where necessary. To rename project components, open the configuration screen for the component and edit the Name field. Links for each project component are provided on the Project Components page.
Project Components Must Be Valid
The validation rules depend on the type of component.
In order for an activity to be valid, it must be configured properly. If an activity has not been configured or is misconfigured, this validation error messages will be returned:
Activity is not configured properly.
This message appears in a few common scenarios:
- When new activities are added to an operation from the component palette, they are are not yet configured, so you may receive this error message if you added a new activity without configuring it yet. To resolve, open the activity configuration screen and configure the activity.
- If the activity is partially configured, or if the individual field validation within the activity configuration has not been met, you may also receive this error message. To resolve, open the activity configuration and complete all required fields with valid input.
If an activity is invalid for some other reason that cannot be readily determined, this error message will be returned:
Activity is invalid.
To resolve, reference the documentation for each activity available under Connectors.
In order for a script to be valid, it must be configured properly. If a script has not been configured or is misconfigured, this validation error messages will be returned:
Script is not configured properly.
This message most commonly appears when you have added a new script to an operation and it is empty. To resolve, open the script configuration screen and then build a script in the editor.
Script is invalid.
To resolve, open the script configuration screen. The text shown along the bottom of the script editor will indicate specific validation for each line of the script. We also recommend testing the script to ensure it is valid. Additional documentation is available under Scripts.
In order for a transformation to be valid, it must be configured properly. If a transformation has not been configured or is misconfigured, this validation error messages will be returned:
Transformation is not configured properly.
This message most commonly appears when you have added a new transformation to an operation and it has not been configured yet. To resolve, open the transformation configuration screen, then configure the transformation accordingly.
In addition, in order for a transformation to be valid, it must not have any validation errors within the transformation itself. To be considered valid, a transformation must meet these rules:
- A mapping cannot contain references to non-existent fields or variables.
- A mapping cannot contain data type conflicts.
- A target loop node cannot have multiple sources.
- A schema must be provided for an adjacent source or target activity.
In addition, certain target fields may require a mapping, or may not allow a mapping. Invalid mappings are visually indicated within the transformation configuration screen (see Transformation Mapping Validity).
Depending on the error, the appropriate variation of these possible error messages will be returned if this rule is not met:
Mapping refers to a non-existent [source / target / variable] field $[path].
Potential data type conflict in mapping.
Target field $[node.name] [must be mapped / cannot be mapped].
Mappings of a target loop node depend upon more than one source loop node.
[Source / Target] schema must be provided.
To resolve, try these troubleshooting tips:
- If you have references to non-existent fields, data type conflicts, or other invalid mappings, either find the invalid mapping and unmap it or check the file schema to make sure all fields are accounted for and have compatible data types. If you have references to non-existent variables, check to make sure the variable exists.
- If you have a target loop node that depends on more than one source loop node, follow the instructions provided in Mapping from a Multi-Instance Source to Single-Instance Target under Nodes and Fields.
- If you have source or target activities adjacent to the transformation, make sure you provide a file schema for each one. File schemas can be provided from within the activity itself during its configuration (see documentation for each connector), or by defining a file schema from directly within the transformation.
In addition, if a transformation is invalid for some other reason that cannot be readily determined, this error message will be returned:
Transformation is invalid.
