When publishing a Flow, you may encounter the following error:

Publishing Flow with validation errors

This means you tried to publish a draft Flow that has validation errors. Flows with validation errors can be saved as a draft, but not published.

This means that while you can save a Flow with errors as a draft, it cannot be published until all validation issues are resolved. Let’s go through how to troubleshoot and fix this issue.

How to Resolve the Error?

Step 1: Identify Validation Errors

Method 1 - Using Flow Builder UI

  • Open the Flow in the Flow Builder UI.

  • The UI will highlight errors and provide explanations.

  • Make necessary corrections based on the error messages.

Method 2 - Using API to Retrieve Flow Details

If you prefer working with the API, you can retrieve the Flow’s validation errors:

Sample API Request:

curl '{BASE-URL}/{FLOW-ID}?fields=id,name,categories,preview,status,validation_errors,json_version,data_api_version,endpoint_uri,whatsapp_business_account,application,health_status' \--header 'Authorization: Bearer {ACCESS-TOKEN}'

This request returns validation_errors along with other details. Review the error messages and address each issue.

Step 2: Revalidate and Publish

  • After fixing the errors, save the Flow as a draft.

  • Run a validation check in the Flow Builder UI or via the API.

  • Once no errors are detected, proceed with publishing.
