Ensure that the client metadata is a valid JSON object. You can use online tools like JSONLint to validate the format of your JSON.
Step 2: Check Required Fields
Review the Auth0 documentation to ensure all required fields are present in your client metadata. Refer to the Auth0 Applications Configuration guide for detailed information.

Ensure that all field values adhere to the expected data types and constraints. For example, URLs should be properly formatted, and boolean values should be true or false.
Step 4: Update Client Metadata

curl --request PATCH \
--url 'https://YOUR_DOMAIN/api/v2/clients/YOUR_CLIENT_ID' \
