An error occurs in Auth0 Forms when a user clicks the resend button on a form that prompts for a verification code. This issue happens because the resend button contains an invalid or outdated flow ID. Update the form definition so the resend button references a valid, existing flow ID to resolve the issue.

When the form attempts to trigger the flow to generate and send a code via an HTTP action, Auth0 generates the following error: 

Error Processing Step Due to Invalid Form Definition

• Auth0
• Forms
• Flows

The resend button within the form contains an invalid or outdated flow_id that references a flow that does not exist.

To resolve the invalid form definition error, verify the existing flows and update the resend button configuration within the form to use a valid flow ID.

1. Open the Auth0 Dashboard and navigate to Actions > Forms.
2. Locate and open the affected form.
3. Select the resend button within the form builder.
4. Update the flow_id property to match the ID of an existing, valid flow designed to generate and send the verification code.
5. Save and publish the updated form.
