• in the case of error occurring in connection sharing

  • when to close connection?
  • when to close handler?

• more fine-grained error triage

#9937 (comment)

Kieran's additions:

• StopIteration with more precision/detail?
• Better exception on composing batch wrongly (Empty batch)
• ServiceBusConnectionError, can it be more precise when the SB doesn't exist?
• ServiceBusError, can it be more precise for invalid credentials?
• Readonly credentials on send, error should be something more precise than ServiceBusError (servicebusauthorizationerror?)
• Passing a string directly to send; typeerror?
• When calling receive() with a max_batch_size > prefetch, error talks about "link credit" which is not very useful to a user. Should wrap this error at the receive() level or something to that effect, mentioning the interplay of prefetch and guiding an actionable mitigation.
