Lots of crashes since upgrading from 3.5.0 to 3.13.1

I think this might be the same thing as #86, but since I'm using different packages, I thought I'd report it anyway.

I'm using Flask-RESTful for some of my API work and I'm getting 500 returned for things like ExpiredSignatureError. I just got this when using with a react admin app I've written:

As a test, I downgraded back to 3.5.0, which I had been using for a while, and am not seeing the issues.

Can you try setting app.config[‘PROPAGATE_EXCEPTIONS’] = True? I bet that will fix the issues for you. That was changed in 3.7.1 (https://github.com/vimalloc/flask-jwt-extended/releases/tag/3.7.1)

[mark-anders]

Thanks! I think that fixed it. I hadn't read all of the release notes, but I see this was done to work around issues in Flask-RESTFul. Sorry about that!

Thanks again!

No problem, glad that fixed things up for you. I’m going to close this issue now, but don’t hesitate to re-open it or create a new one if you run into other problems.

Cheers.
