Error: Cannot find module 'connect-redis'

I just fired up grist using redis, but when I specify REDIS_URL then I get the following error

grist_1  | yarn run v1.22.17

@dugite-code yes that is one way to do it. What kind of build errors are you getting?

I’m going to go ahead and bundle connect-redis so in future this will be simpler https://github.com/gristlabs/grist-core/pull/183 - it is a small self-contained library.

Sorry about that! We need to add connect-redis@3.4.0 as an optional dependency. Does:

yarn add connect-redis@3.4.0

get you going?
