Updating a page (PUT) via REST API returns 500 Interval Server "No content to map to Object due..."

[Sebastian Immoor]

Hi there,

I try to use a PUT request on a page via REST API on a Confluence 6.15.4.

The call is:

wget --quiet \
--method PUT \
--header 'content-type: application/json' \
--header 'authorization: Basic xsdghseuhfeshfwhefhkjf' \
--body-data '{\n "minorEdit": "true",\n "id": "182353945",\n "type": "page",\n "status": "current",\n "title": "Sediment Echo Sounder (Parasound P70)",\n "space": {\n "id": 286982148,\n "key": "EFPW"\n },\n "body": {\n "storage": {\n "value": "<p>Test</p>",\n "representation": "storage"\n }\n },\n "version": {\n "number": 50,\n "message": "Automatically updated by Sensor2Confluence-Transporter (polarstern@binf02p165)"\n }\n}\n' \
--output-document \
- https://localhost/confluence/rest/api/content/182353945

The return is:

{
"statusCode": 500,
"message": "",
"reason": "Internal Server Error"
}

The log file in Confluence contains:

Has anyone an idea? I believe it does not work since the last upgrade. But I cannot find any error in the JSON itself. A GET to that URL works fine. If I change username to a non-existing, I get an 401 Unauthorized. So everything as expected...

Cheers,

Sebastian

Okay I solved the problem.

The problem was indeed a wrong URL I used.
I used https://localhost/confluence/rest/api.
Correct or new (?) is https://localhost/rest/api.

The problem is there is still some kind of redirect from /confluence/rest to /rest so a GET for example worked fine. *But* the redirect somehow cuts off all PUT parameters so every PUT request sent to the API was empty. Really stupid...

CURL seems to work, but WGET and my Python requests-module which was the original intention to use failed.

Try curl!
