schedule() command doesn't defaulty take into account instruction map.

Environment

• Qiskit Terra version: 0.25.0
• Python version: 3.10
• Operating system: Win11

What is happening?

schedule() command fails when the circuit includes 'measure' with the error message

schedule(circuit, backend)  

 qiskit.pulse.exceptions.PulseError: "Operation 'measure' exists, but is only defined for qubits [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26]."

The command works when specifying the default instruction map

schedule(qc, backend, backend.defaults().instruction_schedule_map, meas_map=backend.configuration().meas_map )

How can we reproduce the issue?

 provider = IBMProvider()
 qc = QuantumCircuit(1)
 qc.h(0)
 qc.measure_all()  # or qc.measure(0)
 # Schedule
 qctr = transpile(qc, backend_nisq, initial_layout=None, optimization_level=0)
 sch = schedule(qctr, backend)

What should happen?

default instruction and default measure maps should be defaultly taken into account without having to explicitly specify it in the schedule() command

Any suggestions?

@patdenim , I am unable to reproduce the error as shown by you. This is what I am getting instead! Could you please confirm if you are getting the same, I would like to work on this issue :) I have checked it, the same is the problem with qiskit verison 0.44.2 with qiskit-terra version 0.25.2.

@fvarchon , am I allowed to work on this issue?

[fvarchon]

@MozammilQ Yes for sure :)

@fvarchon , sir, please see if my efforts a good enough :), please let me know if any additional changes are required :)

Thanks @MozammilQ, you've got the point !! fails only when backends are V1.

@to24toro, @nkanazawa1989: was this fully closed by #10988 or is there more to do?

[to24toro]

@jakelishman I think we can close this issue.
