Additional comment.

After doing I found that I have a python script that contain "platform" keyword

grep -r platform
.pipeline/terraform.provider.downloader.py:import platform
.pipeline/terraform.provider.downloader.py:    system = platform.system().lower()
.pipeline/terraform.provider.downloader.py:    arch = ARCH.get(platform.machine())
.pipeline/terraform.provider.downloader.py:        next(filter(lambda os: os["os"] == system and os["arch"] == arch, provider_version_manifest["platforms"]))
```

Closing in favor of #1099 Because after rerun with output yaml just saw that this is the same case
