Duplicate parameter_binds

What is the current behavior?

Qobj is being deprecated so it's probably not worth fixing. But if I assemble() a circuit with an Aer backend, then call its backend.run(), the job would fail with

_run_qobj() got multiple values for argument 'parameter_binds'

because assemble inserts parameter_binds into circuits.config.

Steps to reproduce the problem

from qiskit import transpile, assemble
from qiskit.test.reference_circuits import ReferenceCircuits
from qiskit_aer import Aer

sim = Aer.get_backend("aer_simulator")
bell = ReferenceCircuits.bell()
qobj = assemble(transpile(bell, sim), backend=sim)
sim.run(qobj)

What is the expected behavior?

I can still run a qobj with Aer.

I'm having the same issue.

Run the transpiled circuit directly instead of using QObj. It worked for me.
