I'm trying to build my nx application in github actions with nx cloud enabled. I always get the fatal: No such ref: 'main~1' error.
The command nx affected --target=build --base=main~1 --head=HEAD --parallel --with-deps works before I commit, but after I commit, the command no longer works locally or in ci.
Based on the docs, setting the base to main~1 should just compare it to the previous commit of the main branch.
Full error in Github Actions:
yarn run v1.22.10
$ nx affected --target=build --base=main~1 --head=HEAD --parallel --with-deps
fatal: Not a valid object name main~1
fatal: No such ref: 'main~1'

Run task for affected projects
Run command using --base=[SHA1] (affected by the committed, uncommitted and
untracked changes):
--base Base of the current branch (usually master) [string]
or using --base=[SHA1] --head=[SHA2] (affected by the committed changes):
--base Base of the current branch (usually master) [string]
--head Latest commit of the current branch (usually HEAD) [string]
or using:
--files Change the way Nx is calculating the affected command by

Okay... so I finally figured out what's going on. After logging git show-ref in github actions, I found that the actions/checkout action by default only checks out one commit.
Only a single commit is fetched by default, for the ref/SHA that triggered the workflow.
After specifying the fetch-depth: 0 to fetch all the refs for all the branches, it worked. Nx is able to properly compare the difference between the different branches and previous commits in the same branch.
