This was due to a version mismatch. I was trying to use the database with a previous version of NodeBB by mistake. I'm marking this as solved

I see! Thank you so much for your response!

Hello! I need to create a plugin for a customer and I couldn't find documentation on testing. I'd like to see any examples on github that you recommend for testing plugins.

What sources do you recommend? I'd like to test the plugins using something like Jest or Mocha

I checked and I have a package.json and a package-lock.json file in my home directory

Did ./nodebb reset -p to see if this has something to do with the plugins. However, after I run ./nodebb upgrade (I get a out of date schema error) I get the same error I mentioned in the first post

ReplyError: WRONGTYPE Operation against a key holding the wrong kind of value

Hello, I just did git checkout v1.7.2 but I'm getting the same error.

Thank you so much for the response by the way

Hello everyone, I'm getting the following error while importing a redis database into my current installation

Any help will be very appreciated!
