Answer 1

Which logic app connector are you using?

AFAIK there are two, service bus and service bus subscription.
Judging from your error message you might want to test to disable sessions in Service Bus:

Answer 2

Hi @BlakeneyEric-5139

The error message is expected behavior as looking into backend logs I could see that the subscription (spo***) is session enabled, and the sender sends the message with the session id while the receiver will receive the message only if you are passing the session ID. Further looking into your logic app configuration I can see that you are using the action "When a message is received in a topic subscription (auto complete)" where there is no option to configure the session ID details while receiving the messages.

You need to create the trigger as "When a message is received in a topic subscription (peek-lock)" which has the option to pass the custom session ID or next available session ID. In the below screenshot I have used the session as "Next Available".

Once you have consumed the message you need to create action to complete the message.

Alternative if you want to use "When a message is received in a topic subscription (auto complete)" trigger then your sender application should not send the message using session ID and you need to create a new subscription that should not have "Enable sessions" property enabled. You cannot change this property in an already created subscription.

Hope the above helps in resolving the issue. Please let me know if you have any queries.
