Ok guys so I found a solution!
Whenever we install the gatsby-source-strapi plugin from the plugin store from gtysbyjs.com/plugins just check which version of the plugin you have installed.In this project for me the version was:
“gatsby-source-strapi”: “^0.0.00”. I dont know why this happend, for some reason this version was installed!
Then I checked one of my previous gatsby+strapi website which I did a while ago and there the plugin’s version was different, the version was :“gatsby-source-strapi”: “^0.0.12”,
So I just took my chance and changed the version from “gatsby-source-strapi”: “^0.0.00” to “gatsby-source-strapi”: “^0.0.12” and did a npm install in my shell!
And boom it worked and I would see all my collection types of strapi in the graphql playground!
I don’t know whether this is in an error or what but if anybody knows the reason behind why if we install this plugin from the plugin store we get a 0.0.00 version, please comment down below!
