nanoid: Error: No valid exports main found for '/path/to/nanoid'

As initially described at https://github.com/ai/nanoid/issues/206#issuecomment-622967848 , I am getting a MODULE_NOT_FOUND error with node@13.2.0 and yarn@1.22.4.

Here is the repro: https://github.com/cansin/nanoid-module-not-found-repro

And a sample run on my local:

cansin@localhost nanoid-repro % node --version
v13.2.0
cansin@localhost nanoid-repro % yarn --version
1.22.4
cansin@localhost nanoid-repro % yarn install
yarn install v1.22.4
