Getting permission denied in lambda deployment

[Sabreen-Parveen]

I have deployed codium agent using a lambda function using this guide.
Branch used: main
I am getting this errror:

[ERROR] OSError: [Errno 30] Read-only file system: '/home/sbx_user1051'

Please help me in resolving this issue.

The error you are encountering, [Errno 30] Read-only file system, suggests that your application is trying to write to a file system location (/home/sbx_user1051) which is read-only. This can occur in environments like AWS Lambda where the file system is not writable except for the /tmp directory.

Here are some steps to resolve this issue:

1. Modify Cache Directory Location: The error seems to originate from the Azure DevOps Python SDK trying to create a cache directory. You should modify the cache directory location to a writable path, like /tmp in AWS Lambda environments. You can often set this through environment variables or SDK configuration options.

2. Review Permissions: Ensure that the user under which the application is running has the necessary permissions to write to the desired directory. In serverless environments, you're typically limited to specific directories (like /tmp in AWS Lambda).

3. Update SDK/Library Usage: If you are using an SDK or library that does not support changing the cache directory, consider updating it to a newer version that might have this feature. Alternatively, you might need to look for workarounds or modify the library, if possible.

4. Environment Configuration: Review your environment configuration to ensure it's set up correctly for writable directories. In serverless and containerized environments, file system access can be limited, so understanding these limitations is crucial.

5. Logging and Debugging: Add additional logging around the file operations to get more insights into the failure. This can help in identifying if there are other underlying issues.

6. Code Review: Review your code to ensure you are not unintentionally trying to write to a read-only part of the file system. In some cases, file paths might be hardcoded or incorrectly configured.

7. Consult Documentation: Review the documentation for the environment you are deploying to (e.g., AWS Lambda) and any SDKs or libraries you are using to understand their file system limitations and configurations.

By addressing these areas, you should be able to identify and fix the root cause of the Read-only file system error.

@Sabreen-Parveen
does the issue still exist, or can I close it ?
