Error 500 on gitlab trigger API

Greetings, On our Gitlab CI/CD, we have 5 continuous calls to the trigger API. For like a year from now, it has been working perfectly, but currently, we are having some issues. Exactly, we receive from the API the error: '{"message":"500 Internal Server Error"}' at the second or third call, but always the first one works. We haven’t changed anything so we don’t have any clue of what’s happening.
Here we have to call to the API:

curl -X POST -F token=$CI_JOB_TOKEN -F ref=main

Maybe we are missing something or the API rate limit has been updated?

Thank you for the time :slight_smile: !
