Hello @rogerbarretocode, it's good to see you here again! Let's dive into this issue.

Based on the traceback you provided, it seems like the error is originating from the language_parser.py file in the langchain_community.document_loaders.parsers.language module. Specifically, it's trying to access an attribute COBOL from the Language enum which doesn't seem to exist.

This could be due to a couple of reasons:

1. The Language enum in your version of LangChain does not have a COBOL attribute. This could be because the COBOL attribute was added in a later version of LangChain. You mentioned that you're using LangChain version 0.0.316, but the latest version is 0.0.354. It's possible that updating to the latest version could resolve this issue.

2. There's a bug in the language_parser.py file where it's trying to access a COBOL attribute that doesn't exist or hasn't been properly defined.

To resolve this issue, you could try the following steps:

1. Update LangChain to the latest version (0.0.354) and see if the issue persists. You can do this by running pip install --upgrade langchain.

2. If the issue persists after updating, it's likely a bug in the language_parser.py file. In this case, you could try commenting out the line where the COBOL attribute is accessed as a temporary workaround. However, this could potentially cause other issues if the COBOL attribute is required elsewhere in your code.

If neither of these steps resolve the issue, it would be helpful if you could provide more information about your code and how you're using the AsyncChromiumLoader class. Specifically, it would be helpful to know if you're using the COBOL attribute elsewhere in your code, and if so, how.

I hope this helps! If you have any other questions or need further clarification, please don't hesitate to ask.

I was facing the same problem when I was trying on a local machine, I switched to Colab and not its working fine. Not sure why this happened.

[georgioooo]

And me too i have the same problem

My issue got fixed after uninstalling langchain and installing it again

Based on the traceback you provided, it seems like the error is originating from the langchain_community.document_loaders.parsers.language.language_parser module, specifically when it tries to access Language.COBOL. The Language enum might not have a COBOL attribute in the version of LangChain you're using.

However, you mentioned that the issue was resolved after reinstalling LangChain. This suggests that there might have been an issue with your previous installation of LangChain, possibly a version mismatch or a corrupted installation.

If you encounter this issue again, I would recommend checking the version of LangChain you're using and ensuring it's compatible with the langchain_community package. You can do this by running pip show langchain and pip show langchain_community in your terminal and comparing the versions.

Also, make sure that the Language enum in your version of LangChain includes a COBOL attribute. You can check this by navigating to the langchain_community.document_loaders.parsers.language.language_parser module in your LangChain installation and looking at the Language enum definition.

If the COBOL attribute is not present, you might need to update your version of LangChain or use a different attribute that's available in your version.

For more information, you can refer to the LangChain documentation and the source code of the langchain_community.document_loaders.parsers.language.language_parser module:

• LangChain documentation: https://langchain-ai.github.io/langchain/
• Source code: https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/document_loaders/parsers/language/language_parser.py

I hope this helps! If you have any more questions or need further clarification, feel free to ask.

I faced a similar issue but not for COBOL but for C language defined on the enum, got resolved after upgrading langchain version.
