Probably the same issue as #372 but with a different library. Seems like a new version of the lambda environment is numbering their libraries at the name level.

Change would be here: https://github.com/aws-samples/amazon-textract-textractor/blob/master/.github/workflows/lambda_layers.yml#L355

We will address this issue by the end of the day, thank you for flagging it.

This is fixed in the latest lambda layer version.
