`IllegalStateException: Cannot parse execution result` during Python test generation

[tyuldashev]

Description

Sometime exception Cannot parse execution result is thrown when test are generated for python code.

To Reproduce

Steps to reproduce the behavior:

1. It doesn't happen every time, I faced it on langchaing project
2. Generate tests for langchain.input.get_colored_text or for langchain.input.get_color_mapping

Expected behavior

Tests are generated.

Actual behavior

No tests are generated, exception is thrown. Could it be some length limitation of the strings we pass trough the socet?

Visual proofs (screenshots, logs, images)
Two samples of exceptions:
