Heroku Error: "database connection isn't set to UTC"

[Daniyal Chawla]

When I try to run my project on the Heroku, I get an error that says "database connection isn't set to UTC".

I've already installed Heroku Postgress and Heroku Redis so I'm not why what's wrong.

Help would be appreciated. Thanks!

I saw another report of this yesterday. Seems to be a new issue. Can you show your requirements.txt file?

[Chris @ oTree]

Also can you show the full error traceback?

Thanks for the quick reply! Here you go:

# oTree-may-overwrite-this-file

# IF YOU MODIFY THIS FILE, remove these comments.
# otherwise, oTree will automatically overwrite it.
otree[mturk]>=3.4.0b3,<5
psycopg2>=2.8.4
sentry-sdk==0.7.9

I used almost exactly the same code and steps for a different app a few days ago, and it worked perfectly.

Here is the solution that worked for me:

After a lot of search, I think the problem is described here:

https://stackoverflow.com/questions/68024060/assertionerror-database-connection-isnt-set-to-utc

I followed the instructions to put "psycopg2>=2.8,<2.9" in my requirements file and it solved my problem.

It worked! Thank you so much
