Http 400 when trying to access

[rpinheiro-home]

I followed the initial guide step by step and when trying to access the initial URL I get an http code 400 and in the log only a json appears containing: node:1

What am I missing?

It's more a question than an issue Thanks

I don't know exactly why (because I don`t know flask) but commented this lines and now I can acess.

        # if app.testing:
        # self.logger.debug('view_args of %s\n%s', request.url, self.json_dumps(request.view_args))
        # if request.args:
        #     self.logger.debug('request.args of %s\n%s', request.url, self.json_dumps(request.args))
        # if request.form:
        #     self.logger.debug('request.form from %s\n%s', request.url, self.json_dumps(request.form))

it's seem that werkzeug 2.1.0 got some break change about request.json you can just specific werkzeug version to 2.0.3 will sovle the case https://github.com/pallets/werkzeug/issues/2339

i'm running on zorin os 16 ( ubuntu 20.0.4 base) i been try to fix it but get no where

[casual-silva]

I solved the problem to locate the source code and found it was caused by the Werkzeug version problem As he said, @pandaaaa906 can be solved by lowering Werkzeug

Reinstall >> pip install Werkzeug==2.0.2
