@curla92 does this command fix it?

pip3 install Werkzeug==3.0.1 Flask-Login==0.6.3 Flask-WTF==1.2.1

then restart it

@dgtlmoon Sorry for the lack of context in #1961, I thought the issue would have been tracked properly elsewhere and indeed here we are! I intended to investigate further but didn't have the chance until moments ago.

I updated to the latest version through pip3 install --upgrade changedetection.io as usual, and upon restarting the service I got the same error mentioned here. Hacking in an older version of werkzeug through pip led me to that second error I posted, and rolling Flask back from 2.3.3 to 2.2.3 seemed to solved that issue in a pinch.

Here's a current freeze on the dedicated LXC container I'm running changedetection inside of:

# pip freeze | grep -Ei 'flask|werkzeug|changedetection'
changedetection.io==0.45.7
Flask==2.2.3
Flask-Compress==1.13
flask-expects-json==1.7.0
Flask-Login==0.6.2
flask-paginate==2022.1.8
Flask-RESTful==0.3.9
Flask-WTF==1.0.1
pytest-flask==1.2.0
Werkzeug==2.3.7

Removing all these packages (pip uninstall -yr <(pip freeze | grep -Ei 'flask|werkzeug|changedetection')) and reinstalling changedetection has just yielded me these dependencies:

# pip freeze | grep -Ei 'flask|werkzeug|changedetection'
changedetection.io==0.45.7
Flask==2.3.3
Flask-Compress==1.14
flask-expects-json==1.7.0
Flask-Login==0.6.3
flask-paginate==2023.10.24
Flask-RESTful==0.3.10
Flask-WTF==1.2.1
pytest-flask==1.3.0
Werkzeug==3.0.1

So yeah, it seems like the Flask-WTF version you just pinned solves the curlprit. Thanks!

ok great, i'll cook a new release soon

[dgtlmoon]

@curla92 @nmaggioni ok please try pip3 install --upgrade changedetection.io

that should resolve all problems for you

please let me know that works, it should bump it to 0.45.7.1
