Please provide evidence that PyMuPDF is causing an issue here, and please use English language exclusively: this will help our team and our international users to understand.

An error occurred when dify was deployed locally and the pymupdf plugin was added, but the file could not be read

[JorjMcKie]

Check out whether pymupdf can read the file when provided locally via doc = pymupdf.open("input.pdf").
If that works, then PyMuPDF does not cause the error, but your setup / configuration.

@JorjMcKie Hmm? Is this a similar problem? #4461

[JorjMcKie]

@CTD-Networks-CO-LTD - We are talking past each other:

1. Please store the file in question on your local computer, for instance under the name "input.pdf".
2. Try to open it via doc = pymupdf.open("input.pdf").

Only if the statement under point 2. does not work, we are able to deal with your post.

Background is that we cannot to reproduce your environment without installing additional software ("dify" etc.). This is beyond the scope we can cover here.

BTW: When trying to understand the provided JSON snippets it seems that you are trying to directly open a remote file. This is not supported by PyMuPDF. PyMuPDF can only access files on local disks or as file images resident in memory.
Therefore, non-local files must first be downloaded to either a local disk or provided as memory.
