Additional Information

• qiskit-ibm-runtime version: 0.22

I didn't look too much into this, but a quick Google search says it may be an incompatibility between request and Python 3.10.

For context, the above error was generated when running the code on the IBM Watson Studio. However, It ran smoothly when executing in my local environment.

I replicated the issue in Watson Studio and I resolved uninstalling the simplejson dependency:

!yes | pip uninstall simplejson (Remember restart the kernel after uninstall in jupyter environment, in this case in Watson Studio)

For context: Qiskit/qiskit-ibm-provider#649 (comment)

Thank you @pacomf - yes this same issue we discovered a while back in qiskit-ibm-provider.

It appears that when simplejson is in the environment requests preferentially imports it. However, the arguments accepted by JSONDecoder are inconsistent between the standard library json and simplejson leading to errors when using the standard json.JSONDecoder when simplejson is in the environment.

Closing as resolved

This issue was reported during the quantum challenge when people were running the notebook on qBraid. Is there a plan to add some checks of whether simplejson exist in the environment and raise warnings? This bug is rather hard to debug unless user search on the github repo.

Thanks @HuangJunye it's certainly a non-obvious bug we'll try and fix it asap.

@rryoung98 is this issue fixed. I am still seeing this happen in qBraid. Could you please update?

Hi @JaganNatarajan I'm working on a fix in #1800
