Dear Otree community,

I'm trying to deploy my project through heroku and I keep running into an error on the resetdb step. My project reads a csv that is in the files for values and there seems to be something problematic in the file path. It runs properly locally (on my windows device), but I get the following error when I resetdb. 

I've tried changing from forward to backslashes and with and without the "r" in the file path. I've also checked that the csv file indeed exists where I have in on the heroku server.

Of note is also that in the FileNotFoundError, an extra backslash is inserted that I don't know the origin of.


The error log is the following:

What error do you get when you use a forward slash?

I just retried the process again, it seems like the combination of with the r and forward slash worked (and posting about it). Thanks again!
