Error building component FILE: bad offset for central directory #4695

Open fanimali opened 5 days ago

fanimali commented 5 days ago

Bug Description

it does happen kind of randomly, when loading files using the File component. I am loading txt files.

It happened to me quite a few times repeatedly.

Langflow on Astra (I thinit's version1.1)

Reproduction

steps to reproduce: load one file, build the component, all is good, then load another one, build, all is good then load another one, build and it fails with that error, preventing the build then change the file, build and it loads correctly...

Expected behavior

The File component should not show any error when loading a file, or show a meaningful error if needed.

This error seems to resolve on its own, but then it comes back. It's not blocking though.

Who can help?

The "bad offset for central directory" error you're encountering with the File component in Langflow version 1.1 seems to be an intermittent issue that occurs when loading text files. Unfortunately, there isn't specific documentation or known issues related to this error in the available information. However, you can try the following steps to troubleshoot and potentially resolve the issue:

  1. Check File Integrity: Ensure that the text files you are loading are not corrupted. You can try opening them in a text editor to verify their content.

  2. Logging: Enable detailed logging in Langflow to capture more information about the error when it occurs. This can help identify any patterns or specific conditions that trigger the error. Langflow uses the loguru library for logging, and you can adjust the log level to "DEBUG" for more detailed logs [1].

  3. File Component Implementation: The File component checks file extensions and raises errors for unsupported types. Ensure that the files you are loading are supported text file types like .txt, .md, .csv, etc. [2].

  4. Error Handling: Langflow provides meaningful error messages for unsupported file types. If the error message is not clear, consider checking the logs for additional context [2].

If the issue persists, reviewing the logs might provide more insight into the root cause of the error.

@fanimali Just to confirm, this was happening when uploading regular files (.txt, etc) not zip files, right?

Zip file support is new, and the references im seeing show that this error occurs when involving zip files... but that doesn't seem to be what you experienced. I'm going to see if i can reproduce it. Possibly it could be related to DS LF specifically, as the testing of the file component has primarily been done on the OSS version. But any more details you could provide would be much appreciated!
