MassTransit - Exception during receive message in MassTransit.ReceiveTransport

Question

I get the following weird error when mt tries to receive message from queue.

Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

My consumer is not executed and the message goes to _error queue. We use MassTransit 7.3.0

I don't change anything, the same code works fine on another server (uat).

Clearly, something in your configuration is expecting a Guid value, and it isn't aGuid. The fact this it is happening when trying to resolve a consumer from the container doesn't appear to be the root cause.
