’m experiencing an issue with the local execution environment in ChatGPT.

I have a Parquet file uploaded to the project at:

/mnt/data/ts_target(1).pq

Previously, ChatGPT was able to read and analyze Parquet files from /mnt/data normally. However, it is now unable to access this file at all.

The problem does not appear to be related to the Parquet file itself, because the error occurs before any Parquet parsing takes place.

For example, even very basic operations such as:

• checking whether /mnt/data/ts_target(1).pq exists;
• listing the file with ls;
• accessing /mnt/data through the Python execution environment;

all immediately fail with:

ClientError

I also tried using a separate local/container execution path, and it returned the same ClientError.

Therefore, this seems to be an issue with the ChatGPT local execution environment, sandbox, or /mnt/data file mounting/access layer rather than with the contents or schema of the Parquet file.

The file is still shown as uploaded and its expected path is:

/mnt/data/ts_target(1).pq

Could you please help investigate:

1. Why the execution environment can no longer access files under /mnt/data?
2. Whether the sandbox/file mount for this conversation or project is currently broken.
3. Whether the execution environment can be reset or reinitialized without requiring me to re-upload all of my project files.

This is particularly important because I have multiple large Parquet datasets already uploaded to this ChatGPT project, and they were previously accessible for local analysis.
