This error can occur if we are currently having an issue with the CircleCI service, so if you are getting this error and there is a current active incident that is the likely cause:
However, if you need confirmation feel free to reach out to the support team to confirm that is the root cause.

For each job, a status check is made, and the job name is included and contributes to the character limit. One way to work around this error is to consolidate jobs, or shorten job names, to be below the character limit.
