Jupyter interactive cannot use via remote ssh as it showed chunkLoadError

Issue Type: Bug

When I use remote ssh connected to the ubuntu server, I cannot ordinarily open the .ipynb file and cannot open the interactive window when reading the .py file. When I open the .ipynb file, the remote vscode window will reconnect repeatedly. When I open the interactive window on the .py file, the interactive window cannot normally display, with a notion

I check the Webview developer tools, there are following warnings:

I have the same problem. I am not using .ipynb files, but simple .py files with code sections (# %%). The .py runs just fine in the remote shell, but shows these strange messages when run in the interactive console.

I have encountered a similar problem in scripts where I do not output anything to sys.stdout.

If I execute the following cell from a .py file via SHIFT+ENTER and then inspect x in the interactive terminal, I receive the aforementioned error.

# %%
import numpy as np

x = np.random.rand(3)
# %%
# [inspect `x` in the interactive terminal] -> error

However, I do not get the error when I have printed something in the script prior to the inspection in the interactive terminal.

# %%
import numpy as np

print("init stdout")
x = np.random.rand(3)
# %%
# [inspect `x` in the interactive terminal] -> no error

Following on the discoveries of @janjagusch @PhilippRuchser

System setup Running VS Code on WSL2. Extension versions are:

• Jupyter: 2021.5.745244803
• Python: 2021.4.765268190

Python interpreter is version 3.8.8 installed in an anaconda environment on WSL2 (‘Python 3.8.8 64-bit (‘base’: conda)’)

Workaround

1. Create a new .py file in the working directory
2. Add one line with a print statement (e.g. print(“init stdout”) )
3. Right-click and select Run Current File in Interactive Window

Once the three steps above are complete, I am able to continue using the interactive window and run cells in other files without errors.

Creating and running the file with the print statement:

Subsequently running other files in the same working directory:
