"Internal Error" after creating a MongoDB data source


Installed the latest version of re:dash using the bash script, logged in as admin, created a new mongodb data source and called it “staging_DB”, then I created another data source and by mistake called it also “staging_DB”, I got a “saving failed” msg so I realized my mistake and corrected it to “production_DB”, got another “saving failed”, refreshed the page and got an internal error, this is the relevant trace from the log file:

Can you suggest a way of quick fixing it? re-installing on same machine didn’t help.


The MongoDB query runner expects a Database Name value but doesn’t mark it as required. You probably didn’t set it when creating the data source, and this causes the error.

I guess the easiest way will be to delete the data sources you created with the CLI:

  1. Change dir to /opt/redash/current.
  2. Run: bin/run ./manage.py ds delete staging_DB and run: bin/run ./manage.py ds delete production_DB.

Then recreate the MongoDB data sources with specifying both the connection string and the db name.


(Changed the db name to be mandatory to avoid future instances of this issue: https://github.com/getredash/redash/pull/1234)


manage.py returns error “role “root” does not exist”.


Prefix the commands with sudo -u redash, i.e. sudo -u redash bin/run ./manage.py ds delete....


“sudo -u redash ./manage.py ds delete staging_DB” gives the following error:

It’s as if a table is missing. Can you run sudo -u redash psql -c "\d" and share the output?

Did the first time you ran the bootstrap script it finished without errors?


Experiencing the same issue.
How did you resolve it?

Using Redash 3.0.0+b3134
Output to sudo -u redash psql -c “\d” is :
