No module named 'json' error

I have deployed the Sanbox local source code, and I have updated the python_path to the path of the Miniconda virtual environment (python_path=/root/miniconda3/envs/sanbox/bin/python). However, when I actually use it, it still reports a 'No module named 'json'' error
If I'm deploying with Miniconda, is this configuration not workable?

Start by reproducing the error with the configured python_path, /root/miniconda3/envs/sanbox/bin/python, and verify whether that interpreter can import json. Compare the interpreter used by the deployed sandbox with the configured Miniconda environment; done means the cause is identified and Python execution works or the unsupported configuration is documented.
