When a workflow is saved, a number of validation checks are run against it to detect issues that may (or will) prevent it from working properly. Workflow validation failures fall into one of two categories:

Errors, which prevent the workflow from running.
Warnings, which indicate potential issues with the workflow, but allow the workflow to run.

The Errors and Warnings modal can be used to assist in troubleshooting workflow validation failures.

Viewing Errors and Warnings

To view any errors or warnings present in a workflow, click the View Errors and Warnings button on the canvas title bar. The Errors and Warnings modal will open.

From the Errors and Warnings modal, you can view all validation failures present in a workflow. The modal can be filtered to show only errors or warnings via the Errors and Warnings checkboxes, respectively. Validation failures are presented in a table view separated by task. Click on any failure from the table to be redirected to where the failure occurred.

Error References

The following table provides a reference list of errors that can be found in a workflow.

Draft Error	Description	How to Fix
No config found for adapter `${app}`.	The task adapter is not in the config.	Install the adapter on the current IAP.
Cannot find match for input `"${leftoverModelInput}"` from model.	Task parameters do not match the parameters on the task model. The task model contains a paremeter that is not defined in the task.	Delete and re-add the task on the workflow to save against the correct model inputs.
Cannot find match for input `"${leftoverTaskInput}"` from task.	Task parameters do not match the parameters on the task model. The task contains a paremeter that is not defined in the task model.	Delete and re-add the task on the workflow to save against the correct model inputs.
Output `${output}` does not match model output `${outputName}`.	Outgoing variable in task does not match the name of the output defined on the model.	Delete and re-add the task on the workflow to save against the correct model output.
Method not found.	The adapter task method is not defined in the adapter config.	Restart the adapter. If the method is still not found, replace the task with a valid adapter task.
No applications found.	No applications in the config.	Check that the application is present in the services page and restart the application.
Package not found.	Package not found in the config.	N/A
Input `${inputName}` is not a valid name according to platform naming conventions.	A model input of a task does not follow IAP naming conventions.	Fix the invalid name using a valid name.
Output `${outputName}` is not a valid name according to platform naming conventions.	The model output of a task does not follow IAP naming conventions.	Fix the invalid name using a valid name.
Referenced job variable `"${varName}"` is not a valid name according to platform naming conventions.	The reference job variable of a task's incoming variable was edited in a way that makes it invalid.	Fix the invalid name using a valid name.
Outgoing job variable `"${varName}"` is not a valid name according to platform naming conventions.	The outgoing variable of a task was promoted to a job variable and edited in a way that makes it invalid.	Fix the invalid name using a valid name.
Error job variable `"${varName}"` is not a valid name according to platform naming conventions.	The error variable of a task was promoted to a job variable and edited in a way that makes it invalid.	Fix the invalid name using a valid name.
Task cannot contain `${state}` standard and revert transitions.	A task contains a revert and standard transition of the same state (success, failure, or error).	Remove either the standard or revert transition with a duplicate state from the invalid task.
Task must contain only one `${state}` revert transition.	A task contains two revert transitions of the same state (success, failure, or error).	Remove any duplicate state revert transitions from the invalid task.
Manual tasks require "groups" array to contain at least one active group.	A manual task can have zero groups specified or one group or many active IAP groups.	Either add an active group to the manual task or remove all its groups.
Manual tasks require "view" key with path to task view.	A manual task does not contain a view, although it is required by all manual tasks.	Provide a valid view in the `pronghorn.json` for the task.
Invalid transition object requires keys: "type", "state".	The automation contains a transition that is missing the type and/or state properties.	Replace the invalid transition with a valid transition.
Invalid "from" task is not found in task list.	The automation does not contain the "from" task in the transition.	Replace the invalid transition with a transition that contains a valid "from" task.
Invalid "to" task is not found in task list.	The automation does not contain the "to" task in the transition.	Replace the invalid transition with a transition that contains a valid "to" task.
Invalid "type" for transition; must be one of `${types}`.	The transition has an invalid type.	Replace the invalid transition with a valid transition type: "standard" or "revert".
Invalid "state" for transition; must be one of: `${state}`.	The transition has an invalid state.	Replace the invalid transition with a transition with a valid state of "error", "failure", or "success".
Transition is part of a cyclic path.	The automation contains standard transitions that create a cycle.	Remove a transition to prevent cyclic paths.
Revert transitions must be from a future task to a previous task.	The automation contains a revert transition that moves forward in the automation.	Remove the offending revert transition.
Loop transitions can only exist from loop tasks (i.e. "forEach") to other tasks.	The automation contains a loop transition from a task that is not `forEach`.	Remove the offending loop transition.
Task cannot be scheduled without at least one enabled run window day.	Run window for a scheduled task is not defined.	Set a run window for the scheduled task.

Warning References

The following table provides a reference list of warnings that can be found in a workflow.

Warning	Description	How to Fix
Invalid incoming static variable value `${variableName}` is required but no value was provided.	A non-string incoming variable for a task is marked as required, but the field is left empty.	Provide a valid value for the required variable in the invalid task.
Invalid incoming static variable value `${variableName}` is of type enum but has a non-enumerated value `${variableValue}`.	A static variable is of type enum, but the value input is not of type enum or string.	Provide a valid value for the required variable in the invalid task.
Invalid incoming static variable value `${variableName}` should be of type `${variableType}` but is of type `${typeof variableValue}`.	The static variable type does not match the type defined on the task.	Provide a value of the correct type for the offending variable in the invalid task.
