Encountered issues run the pipeline in agent tap when using different parser

[Yeon1007]

When i try to run a pipeline in agent tap, there are some issues when choose to use different parser (already install the minerU and docling):
MinerU: [ERROR][MinerU] Process failed with exit code -9
Naive: ValueError('Parser_0: PDF VLM language does not support empty value.')
Docling: [ERROR]Model(Docling@None) not authorized
How can i fix these issues?

Hi @Yeon1007! I'm Dosu and I’m helping the ragflow team.

Here’s how to address each parser error:

MinerU: [ERROR][MinerU] Process failed with exit code -9
Exit code -9 means the MinerU process was killed, usually due to running out of memory or hitting resource limits. Try reducing the chunk task page size, processing one document at a time, and ensuring your server has enough RAM. If you’re running multiple tasks in parallel, lower the concurrency settings (e.g., set MAX_CONCURRENT_CHUNK_BUILDERS=1). Also, make sure you’re using compatible versions of MinerU and RAGFlow, and check for missing fields like 'bbox' in your PDF blocks if you’ve customized the code. More details: source, source.

Naive: ValueError('Parser_0: PDF VLM language does not support empty value.')
This error happens when the parser expects a non-empty language field for certain VLM-based PDF parsers. If you’re using a parser that requires a language (not DeepDoc, Plain Text, MinerU, or TCADP), make sure to specify the lang parameter in your pipeline config. For the naive parser, this usually means the PDF content is empty or not supported (e.g., image-only PDFs). Try using a stronger parser (like Docling or MinerU) for ingestion, or pre-process the PDF to extract text before uploading. See: source.

Docling: [ERROR]Model(Docling@None) not authorized
This usually means the Docling model is not properly installed or authorized. Make sure you have the docling Python package installed and set the environment variable USE_DOCLING=true. If you’re running in Docker, update your .env file and rebuild/restart the container. If you still see authorization errors, check if Docling requires additional credentials or configuration in your environment. Details: source.

For all parsers, after changing parser settings or updating environment variables, delete and re-upload your PDFs for the new parser to take effect. If issues persist, check backend logs and confirm all required services are running.

To reply, just mention @dosu.
