Fixing approach

1. Create a fork branch from the branch that fail

• test(rust): doc artifact #112
  and modify the possible thing that may cause error
• 9d645f2

build:
   SAVE ARTIFACT target/$TARGETARCH/doc doc

After the modification, the CI pass

2. Then trying to revert the changes, CI pass

• 2d12aff

3. Made changes to original branch to test whether, the changes made in 1 fix the issue CI fail

• 8583611

4. Merge the changes to the fork branch CI fail

• 3224e98

5. Try removing --no-cache within the fork branch CI pass

• 331e56a

Goal

• Investigate the root cause of the problem (might be caching problem/ syntax problem)
