Environment

• Qiskit version:

qiskit                    1.2.4
qiskit-aer                0.15.0
qiskit-aer-gpu            0.14.2
qiskit-algorithms         0.3.0
qiskit-ibm-provider       0.11.0
qiskit-ibm-runtime        0.30.0
qiskit-qasm3-import       0.5.0

• Python version:

Python 3.12.2 | packaged by conda-forge | (main, Feb 16 2024, 20:50:58) [GCC 12.3.0] on linux

• Operating system:

Ubuntu 24.04.1 LTS x86_64

What is happening?

A numpy type error raised during the execution of qiskit.qasm3.dumps .

How can we reproduce the issue?

from qiskit import QuantumCircuit
from qiskit.quantum_info import random_unitary
from qiskit.qasm3 import dumps

qc = QuantumCircuit(4)
for i in range(4):
    qc.h(i)
    qc.append(random_unitary(2),[i])
    
print(qc.draw())

dumps(qc)

or

from qiskit import QuantumCircuit
from qiskit.quantum_info import random_unitary
from qiskit.qasm3 import dumps

qc = QuantumCircuit(4)
for i in range(4):
    qc.h(i)
    qc.append(random_unitary(2).to_instruction(),[i])
    
print(qc.draw())

dumps(qc)

What should happen?

I should be able to dump this circuit to QASM3 because qiskit.qasm2.dumps can successfully dump this circuit.

Any suggestions?
