Hello @Leidy Alexandra Jimenez Moncada ,
Thanks for the question and using MS Q&A platform.
As per my understanding, you are receiving the above error message while trying to access Odata Microsoft Usage Analytics using ADF. Please correct if my understanding is wrong.
From the error message, it seems like the response content type isn't supported. Supported response content type is 'application/json
As mentioned in the error, could you please check the response from other clients like your browser or POSTMAN. Also, I would suggest giving a try with serviceurl+"/$metadata"
and see the behavior.
Do let us know how this test goes.
Thank you
