'morph execute' (morph-cli) uploads code directly via ApiController#run_remote, which creates a Run with no associated Scraper record at all - the code was never synced from a git repo (see the existing comment at Morph::Runner#compile_and_start_run: 'If the run is not part of a scraper (e.g. through the api) then there won't be a git repository'). Because platform selection was 'run.scraper&.platform', every api-triggered run silently fell through to Morph::DockerRunner::DEFAULT_PLATFORM (cedar-14) regardless of what the scraper's own platform file said - discovered by triggering a real scraper (platform: heroku-24) via morph-cli and getting cedar-14's old Bundler::LockfileError instead. The uploaded tarball already includes the scraper's platform file if it has one (morph-cli uploads every file in the directory). Extracted the file-reading logic shared by Scraper#platform into Morph::PlatformFile, and added Run#platform which uses the associated scraper's platform when there is one, falling back to reading the platform file straight out of the already-unpacked run.repo_path when there isn't. Specs included (Morph::PlatformFile and Run#platform) but not executed in this session - didn't want to stand up the full docker-compose/mysql/redis/ elasticsearch stack for this. Traced the logic by hand and syntax-checked every touched file; CI should be the real gate here. Co-Authored-By: Claude Sonnet 5 <[email protected]>

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Handle a directory named platform.
When an API upload contains a root-level platform/ directory, ApiController#run_remote unpacks it and invokes Morph::Runner#compile_and_start_run without a scraper. The method sets started_at before run.platform calls Morph::PlatformFile.read. File.exist? accepts the directory, but File.read raises Errno::EISDIR. No rescue or normal error path handles this exception, so the request fails and the run remains started without finished_at or status_code.
Use File.file? and add a spec that creates a platform directory and expects nil.
Proposed fix
- platform = File.read(platform_file).chomp if File.exist?(platform_file)
+ platform = File.read(platform_file).chomp if File.file?(platform_file)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

@Br3nda the bugs raised by coderabbit appear to be genuine. Can you review and re-request approval.

What does this do?
Makes api-triggered runs (
morph execute/ morph-cli) honor the scraper's ownplatformfile, instead of always silently building againstDEFAULT_PLATFORM(cedar-14).Why was this needed?
ApiController#run_remoteuntars uploaded code straight intorun.repo_pathand creates aRunwith noscraperassociation at all - there's no git repo involved. Platform selection wasrun.scraper&.platform, which is alwaysnilfor these runs, so everymorph executerun silently fell through tocedar-14regardless of what the scraper's ownplatformfile said.Found this by triggering a real scraper (
platform: heroku-24) via morph-cli and gettingcedar-14's oldBundler::LockfileErrorinstead of a heroku-24 build.What changed
Scraper#platformintoMorph::PlatformFile.read(repo_path).Run#platform, which uses the associated scraper's platform when there is one, and otherwise reads the platform file straight out ofrun.repo_path- which already has the uploaded code unpacked into it by this point, including theplatformfile if the scraper has one (morph-cli uploads every file in the directory, this wasn't a client-side gap).Morph::Runner#compile_and_start_runnow callsrun.platforminstead ofrun.scraper&.platform.Testing done
Specs added (
spec/lib/morph/platform_file_spec.rb, plus a new#platformblock inspec/models/run_spec.rb) but not executed in this session - didn't want to stand up the full docker-compose/mysql/redis/elasticsearch stack for a change this size. Traced the logic by hand against the actual source and syntax-checked every touched file. CI should be the real gate here - flagging this clearly rather than claiming it's verified when it isn't.Opening as a draft for the same reason.
