upload.go:
- Update → Patch (MergeFrom) to avoid resourceVersion conflict when operator
modifies Function between Get() and Update()
terraform provider v0.1.1:
- trigger_resource.go: trToModel returns StringNull() for empty schedule
(fixes 'provider produced inconsistent result' for http triggers)
- main.go: bump version to 0.1.1
examples/pg-query:
- handler.py: fix column name started_at → created_at (matches migrations/001)
- main.tf: pin provider to ~> 0.1.1
.gitignore: add terraform state, lock, .terraform/, handler.zip
doc/errors/log.md: documented all 5 errors from this session:
- resourceVersion conflict → use Patch
- terraform inconsistent result for schedule → StringNull
- terraform import not implemented → delete+recreate workaround
- wrong column name → check migrations before writing handlers
- Deployment not restarting after image rebuild → rollout restart / TODO: restartedAt annotation
doc/progress.md: terraform apply e2e ✅
