AWS Batch job retry strategy

Hi, we have an AWS Batch job with defined retry strategy. We followed the introducing blog article. It should retry the job 5 times when it encounteres the ResourceInitializationError status reason. This is how the error reads in the documentation. It worked well however today we received this error for which the job was not retried:

Resourceinitializationerror: unable to pull secrets or registry auth: execution resource retrieval failed: unable to retrieve ecr registry auth: service call has been retried 3 time(s): RequestError: send request failed caused by: Post "https://api.ecr.eu-central-1.amazonaws.com/": dial tcp: lookup api.ecr.eu-central-1.amazonaws.com: i/o timeout

Notice the lowercase i and e in the Resourceinitializationerror. I couldn't find anything about the error being renamed except a 2 weeks old discussion somewhere on GitLab or Gitter where the error is also mentioned with the lowercase letters. Was it renamed or is this just a one-shot typo (even though I can't imagine how that could happen)?
