[BUG] pdf flow results in ==> message: 'PDFDocument: stream must have data'

[ashokrs]

Installed Flowise on my ubuntu instance on AWS EC2. Created a pdf flow workflow. Put all the keys required. Uploaded a pdf document via the PDF parser component. Then, opened the chat interface and got an error.

@ashokrs I think @HenryHengZJ has added the pull request for this issue.

[ashokrs]

@govind-kumarr thanks. However, I ahd an fortunate accident as the system worked by just doing as described below: I exported the flow as a JSON file and saved it. Navigated to the previous screen. Came back and loaded the same workflow again. This time, it worked. Those errors went away.

I could run "Flowise" by logged in via "x2go" to the EC2 instance as well as configuring the firewall rules and able to launch on my laptop's web browser @ home. No issues. All good.

dont think ive seen this error before. Is it resolved now @ashokrs ?

[ashokrs]

Yes. Resolved. As I said, after the error I had an fortunate accident as the system worked by just doing as described below: I exported the flow as a JSON file and saved it. Navigated to the previous screen. Came back and loaded the same workflow again. This time, it worked. Those errors went away.

I'm encountering the same error:

Should I submit a new issue?
