Issue with HTTP Request (Content Length)?

I am having an issue with the POST and PATCH methods in the HTTP Request Flow Function. GET and DELETE work properly however I get an error 400 when including a body. I am able to use the exact same body in Postman with success. I think I’ve narrowed it down to the “Content-Length” header coming out of AppGyver. In this example the working Postman header shows Content-Length: 25

Whereas the falling AppGyver call shows a content length of 31


If I manually set the Postman header to 31 I get the same error response as AppGyver. The body is 25 characters long. I don’t see any way to override the AppGyver Content-Length header. Any suggestions on what to try next?

For additional context this is the error I receive:

{“odata.error”:{“code”:"",“message”:{“lang”:“en-US”,“value”:“The request is invalid.”},“innererror”:{“message”:“patch : An error has occurred.\r\n”,“type”:"",“stacktrace”:""}}
