There was a recent migration, referring the below document: https://qiskit.org/ecosystem/ibm-provider/tutorials/Migration_Guide_from_qiskit-ibmq-provider.html
Before this migration, I was using IBMQ for submitting jobs on IBM quantum devices. But after changing the function from IBMQ to IBMProvider, my jobs are failing with the below message:
QpyError: "Object type '<class 'qiskit.pulse.schedule.Schedule'>' is not supported in Program namespace."
I'm not sure why I'm not able to submit the same jobs on the same machine. I just changed the interface through which I was interacting with IBM quantum backends.
