[WSGI:ERROR] No commit has been made, due to the following error: "NAME-OF-ENDPOINT"

[GabrieleCalarota]

Describe the bug
Since I've integrated the flask-monitoringdashboard into flask apps with just this 2 lines of code in every file with a flask app (in order to have a share dashboard for every app)

dashboard.config.init_from(file=os.path.join(os.path.dirname(__file__), fileName_dashboard_config))
dashboard.bind(app)

I've started noticing this error in apache2/error.log

[WSGI:ERROR] No commit has been made, due to the following error: "NAME-OF-ENDPOINT"

Where NAME-OF-ENDPOINT is every name of my endpoint on flask API that I've been calling on production server.
Can't say if it's correlated but my API with a WSGIScriptAlias have been stuck in "pending requests" and made my system not working/working only in particular scenarios

Screenshots

Desktop (please complete the following information):

• OS: "Ubuntu 20.04.1 LTS"

Additional context
Flask is running on virtualhost apache configuration like below port 443

<IfModule mod_ssl.c>
<VirtualHost 0.0.0.0:443>
....

I've tried to search on past issues but the only one with a not so similar error is #324

Hi,
I got this error too using default database configs. Then I switched to using postgres, and I get a new error similar to previous one

here is how make the configurations:

dashboard.config.database_name = "postgresql://{}:{}@{}:{}/{}".format(DB_CONF.get("user"), DB_CONF.get("password"),
                                                                      DB_CONF.get("host"), DB_CONF.get("port"),

dashboard.bind(app)
