Describe the problem/error/question
Hey dear community! I’m sending a PUT request to a widget API endpoint and receive the error “Only absolute URLs are supported”, even when the URL is using an absolute path. I’ve tried sending the same request via Postman and that to my surprise works with having copied the same body, headers and URL, which then makes me think something happens on node level when the response comes in. Also, all other HTTP methods work (GET, HEAD, OPTIONS, POST). For nondisclosure purposes, I’ve covered most of the sensitive data. Hope you understand and still are having enough info to support me with this!
Now, my questions: How I can fix it for my running self-hosted instances? Could it be that the response of the endpoint is causing this or could it be something else? And is there any chance of debugging this and see the full request + response objects? Could it be a misconfiguration of the proxy?
What is the error message (if any)?
