InternalServerError when setting circuit.probability() for device execution

0

Running the Superdense_Coding example - and it runs fine using SV1 simulator, however, when I change the device to IonQ or Rigetti, I (AwsDevice("arn:aws:braket:::device/qpu/rigetti/Aspen-8") or AwsDevice("arn:aws:braket:::device/qpu/ionq/ionQdevice")) I get the below error before the task even gets queued:

InternalServiceException: An error occurred (InternalServiceException) when calling the CreateQuantumTask operation (reached max retries: 4): InternalServerError

The error occurs on this line: circ.probability()

If I remove that line, the task gets queued, but there is an index our of bounds error on the response (I assume because the result format hasn't been defined).

Anyone else come across this yet?

Hi DankQ, thanks for flagging this. I was able to reproduce the error, and we are investigating this specific notebook to identify the root cause of this error.

This bug is now fixed, you should no longer see this error when running the example notebook. Thanks!
