@FrozenPandaz Sorry to reply in this issue after it has been closed. I have found the solution. You were right, i created my workspace like 4 months back, that time the base/root tsconfig file named it as tsconfig.json. And i believe from NX 10, it was renamed to tsconfig.base.json. That was the cause of the problem.

So for anyone having the same issue, rename your root tsconfig.json to tsconfig.base.json and rename all the other tsconfig files which extends from root tsconfig.

Thanks.

just adding the following on the tsconfig.json:
"compilerOptions": { "baseUrl": ".", "rootDir": "." },

worked for me… as a temp solution.
