This topic describes common issues with Dify instances and their solutions.
Basic Dify usage
Why do I receive the "No dify api key found in request" error when I call a Dify API?
Obtain the API key (DifyApiKey) for Dify on DMS and add the DifyApiKey to the request headers.
Why can't I set the API key for a model provider plugin?
