    Getting this error from a data action but the header when viewed in Postman doesn't show that. EST call for action execute failed. Message:We were unable to process the response from the remote endpoint because it had a 'content-type' header of 'text/html' instead of the required value of 'application/json'. [6729e479-6f05-4ce7-ba02-74d520397e8b

    Rest API works in POSTMan the header information especially the Content-Type looks correct. Thoughts?

    HTTP/1.1 200 OK

    Content-Type: application/json

    Hi agilio!

    Two things come to mind. First, you can try the standard "Unexpected failure" fix: https://help.mypurecloud.com/articles/custom-action-fails-for-unexpected-reason/

    The other thing that comes to mind is to take a look at the postman console and make sure that there wasn't a redirect that is confusing things. By default postman will silently follow 3xx redirect messages.

    Any additional troubleshooting is going to have to go through customer care / support.

    Thanks the transfer encoding was it. Any chance the error that comes back could be tailored to provide that as the reason versus the content-type error?

    Try setting a "Transfer-Encoding" header to "chunked" in postman and see what you get back.

    LOL nothing says helpful when the error returned is Just "ERROR". I get the challenge

    Thanks for the help.
