Hi,
This error:
"WorkflowOperationParametersExtraParameter – The API operation does not contain a definition for parameter 'item/source'"
usually means that one of your actions is referencing an old or invalid parameter that no longer exists in the connector schema.
A few quick things to check:
-
Check dynamic content / expressions
Somewhere in your flow (often inside Apply to each or a custom action), there is likely a reference like:
If the connector/action no longer returns source, the flow fails to save.
-
Re-select fields instead of typing manually
Open the failing action:
This ensures it matches the current schema.
-
Check renamed or updated actions
If the flow was:
Some parameters (like source) may no longer be valid.
-
Focus on Apply to each
Since your flow has an Apply to each, check inside it:
-
Quick fix (most common)
Delete and re-add the action that is throwing the error (often resolves schema mismatch issues).
If this gets resolved, it would be great if you could share what worked for you. It will help others in the community who might run into the same issue.
