Status Code 308: Sending request to API through gitlab-ci

I’m using gitlab.com on version Enterprise Edition 14.9.0-pre aaa23f2dbf9.

I created a project access token so I can open the MR through the API in gitlab-ci, but I’m getting the result 308.

Command Curl in gitlab-ci:
curl --verbose -o resposta.json -X POST -H "PRIVATE-TOKEN: ${CI_PUSH_TOKEN}" -d "'${MR_DATA}'" https://www.gitlab.com/api/v4/projects/${CI_PROJECT_ID}/merge_requests

And when I take the CURL instruction and run it through my machine it opens MR.

HTTP status code 308 means “permanent redirect”. I believe you’re seeing this because you’re using www.gitlab.com as the base URL instead of gitlab.com

Can you remove the www. from the URL you’re using and verify if you still see a 308 status code?
