Describe the problem/error/question
Hi all,
A bit of a context.
I’m new to n8n, I’m not a programmer now, I had experience in cryptography and secure programming, I’m an expert in Document Management Systems, associated processes and automation (that, in fact, touches everything in a company), digital enterprise/PA, blah blah…I have 20+ years of experience…
This problem seems the same as HTTP Request ignore body with REPORT method but with a little difference.
I was trying to use the CALdav node, but unable to force it to ignore SSL issues due to a self-signed certificate, I switched to the HTTP request node.
I managed to successfully execute PROPFIND and REPORT requests in v1.115.2.
REPORT request was giving the 406 error until I added “name”: “Depth”, “value”: “1”, “name”: “Accept”,
“value”: “application/xml” and “rawContentType”: “application/xml” instead of text/xml.
Then I upgraded to 1.115.3 : and the strange happened.
At the very first execution the node was successful, from the second on the same 406 error was thrown.
If I execute the curl code from terminal it works flawlessly (and by the way, it is not imported correctly in the HTTP Request using the “import cURL” function).
curl --insecure -X REPORT -u user:pwd -H “Content-Type: application/xml” -H “Depth: 1” -H “Accept: application/xml” --data ‘<C:calendar-query xmlns:D=“DAV:” xmlns:C=“urn:ietf:params:xml:ns:caldav”><D:prop><D:getetag/><C:calendar-data/></D:prop><C:filter><C:comp-filter name=“VCALENDAR”><C:comp-filter name=“VEVENT”><C:time-range start=“20251015T220000Z” end=“20251016T215959Z”/></C:comp-filter></C:comp-filter></C:filter></C:calendar-query>’ https://ip:port/caldav/account/home
What is the error message (if any)?
Your request is invalid or could not be processed by the service
REPORT body contains no XML data!
