Seems to be failing on step 2 for me which is Split PDF into Pages

[miles-dev33]

HTTP server responded with error code 503 in step "2. Split PDF into pages", routine "main", line: 48 { "body": "Service Unavailable", "code": 503, "headers": { "Alt-Svc": "h3=\":443\"; ma=2592000,h3-29=\":443\"; ma=2592000", "Content-Length": "19", "Content-Type": "text/plain", "Date": "Fri, 03 Nov 2023 17:47:53 GMT", "Server": "Google Frontend", "X-Cloud-Trace-Context": "853a3ce82faa491cbd266fd3aa572001;o=1" }, "message": "HTTP server responded with error code 503", "tags": [ "HttpError" ] }

Any ideas?

Has to do with a dependency issue with Werkzeug: File "/usr/local/lib/python3.10/site-packages/flask/init.py", line 7, in from .app import Flask as Flask File "/usr/local/lib/python3.10/site-packages/flask/app.py", line 27, in from . import cli File "/usr/local/lib/python3.10/site-packages/flask/cli.py", line 17, in from .helpers import get_debug_flag File "/usr/local/lib/python3.10/site-packages/flask/helpers.py", line 14, in from werkzeug.urls import url_quote ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.10/site-packages/werkzeug/urls.py)

Here's a related stackoverflow on it: https://stackoverflow.com/questions/77213053/importerror-cannot-import-name-url-quote-from-werkzeug-urls

Tried updating the pdf-splitter dependancies to: flask==2.2.2 and adding Werkzeug==2.3.7

But that didn't do the trick either.

Also, tried upgrading flask with: pip install --upgrade Flask

which resulted in: Successfully installed Flask-3.0.0 Werkzeug-3.0.1

and that's a good version of Werkzeug since there was a security vulnerability in the prior version, but to no avail I received the same error after. Which is somewhat expected since the stackoverflow post mentioned that: "Flask 2.2.2 isn't made for Werkzeug 3.0.0"

Going to try pip install Flask==2.0.1 pip install Werkzeug==2.2.2

I FINALLY GOT IT WORKING!!!!

Solution: Update all of the requirements.txt files in the following directories dlp-runner, findings-writer, pdf-merger, and pdf-splitter to have Flask==2.1.2 and Werkzeug==2.3.7, since each of those will try to install Werkzeug 3.0.1 which no longer is combatable with the version of Flask that is installed due to backwards compatibility issues.

Hey @milesjmccloskey , thanks for reporting the issue and digging out the solution. We'll be pushing out a fix with your recommendations (as well as updated libraries and dockerfiles) in the next few days :)

I'll keep you posted and close this issue once we push a fix.

@milesjmccloskey, I went ahead and upgraded the python libraries to fix this issue. Please checkout the latest code and give it a try.

Thanks for reporting the issue and suggesting a fix.

Let me know how it goes and if you find any other bug.

I updated to using those new libraries and still received the error by the way: ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.10/site-packages/werkzeug/urls.py)

The issue is that Werkzeug 3.0.1 and latest Flask library doesn't specify the dependency correctly:

The root cause of this is that Werkzeug 3.0.0 removed previously deprecated code: https://werkzeug.palletsprojects.com/en/3.0.x/changes/#version-3-0-0

Granted it would be ideal if Werkzeug 3.0.1 worked since it fixed a security vulnerability

The solution to get the project to work for me was having to add: Werkzeug==2.3.7

to all of the requirements.txt files
