Module does not update to latest tag on Terraform Enterprise

Problem: 

When publishing a new module version on Terraform Enterprise, it fails with no clear error messaging in the UI.

Solutions:

You can often verify the reason for your module version failing to upload by reviewing the logs in tfe-sidekiq. The below list is not an exhaustive list of reasons, but provides some examples that can be searched for. 

WARN: ActiveRecord::RecordInvalid: Validation failed: Version has already been taken

To resolve, try a different version number. 

"status":"reg_ingress_failed","error":"error loading the module: Invalid configuration_aliases value: Configuration aliases must be prefixed with the provider name. Expected \"azurerm\", but found \"$WRONGALIAS\" (in providers.tf on line 5)"},

To resolve, refer to the invalid configuration_aliases error line as it will indicate the line and file where the error occurs. In the example above, the error is in providers.tf on line 5.

Outcome:

If you're unable to determine the cause of the error, please generate a support bundle and open a ticket with Hashicorp Support.
