Confluence 7.13.7 API Request Returns HTML Instead of JSON

[Goonawardanar_R_N_W]

In Confluence 7.13.7, my API calls are unexpectedly returning HTML content rather than JSON. I've checked my request headers and ensured Accept: application/json is included. Is there a known issue or configuration setting I might be missing that could cause this behavior?

I have the same issue. Any updates?

Dear @Goonawardanar_R_N_W ,

before you proceed, I strongly recommend to upgrade to at least 7.19.x.

Nevertheless have you tried to copy & paste the REST GET call to a browser tab? Does it return also HTML instead of JSON?

Have you tried another REST client or browser extension?

Have you tried

https://example.com/rest/api/content/{id}

instead of

https://example.com/confluence/rest/api/content/{id}
