internal errors for platform string
Metadata
Current evaluation
testcraft pack crashes with AttributeError when a platform value is a string instead of a dict. The bug is still present in current code; _vectorise_platforms calls data.get() without guarding against str values.
Suggested action: keep open
Reason: The bug is confirmed still present in the current codebase: _vectorise_platforms in craft_application/services/project.py calls data.get("build-for") without checking isinstance(data, str), so a string platform value like 'my-platform: amd64' will still crash with AttributeError. The issue is labeled 'Status: Triaged' and 'Type: Bug', indicating maintainer acknowledgement. No fix commit has been found in the git history addressing this specific case. The fix is straightforward (add a str guard before calling .get()), so it should remain open for resolution.
