Unable to load handler matching mongoose: Cannot find module 'mongoose'

[MRVDOG]

Hi, when trying to add a mongodb data-source and create an API to use it, I get the following error in the gateway container logs, I know this is a gateway issue, but I felt it would be best here as I used the docker composer to build my stack.
any assistance would be greatly appreciated, thanks :)

I also want to add, that I ran through the guided tour to add the pets API, and that works perfectly

resolved, added && yarn global add mongoose before && graphql-portal in the container command.
"/bin/sh" "-c" "echo 'Waiting for 10 seconds for Dashboard to come online...' && /bin/sleep 10 && cd /opt/graphql-portal && yarn global add mongoose && graphql-portal"
