Internal error on calling /mine [GET]

pheu commented 4 years ago

I followed the instruction. Tried http://localhost:80/mine in postman.

> docker run --rm -p 80:5000 blockchain
 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)

Btw. The strange thing is that it shows it's running on 0.0.0.0 instead of 127.0.0.1.

It's no problem that it's running on 0.0.0.0, you can hit the endpoint at http://localhost:5000.

As for the error, Flask has a dependency that received a major version update somewhat recently. The easiest fix is to upgrade your version of Flask by running pip install --upgrade Flask.
