Describe the bug Example in file throws an error: https://github.com/Qiskit/qiskit-ibm-runtime/blob/main/qiskit_ibm_runtime/qiskit_runtime_service.py IBMInputValueError: 'Param (circuit_indices) missing required value!'
Steps to reproduce Copy the example in quantum-computing.ibm.com after QiskitRuntime account is saved.
Expected behavior Code works.
Suggested solutions add params.circuit_indices = 0 or make circuit_indices parameter optional as it is not needed when a single circuit is provided.
Additional Information When adding circuit_indices I get:
UserWarning: The qiskit version used to generate the provided QPY file, 0.20.0, is newer than the current qiskit version 0.19.2.
