Hi, @ASarna2. Thanks for your question.

It sounds like your `Content-Type` header isn’t set to `application/json`. But without further details or code snippets, it’s difficult to provide a more specific solution.

Please share more details about your server setup and the code you’re using to handle requests. Otherwise, it will be challenging or impossible for the community to assist you.

Best,

Jaycee
