feat: report package manager and Composer failure codes in telemetry by AmanVarshney01 · Pull Request #109 · prisma/create-prisma

AmanVarshney01 · 2026-09-21T10:36:01Z

Two new allowlisted properties on cli:create_prisma_next_command_failed:

package-manager-error-code: the package manager's own identifier from captured install output (npm E…, pnpm ERR_PNPM_…/E…, Yarn Berry YNxxxx). Dependency installation is the largest failure bucket (25 of 82 for 0.13.1) and arrived with only an exit code. Bun, Deno and Yarn Classic print no stable identifier and report null, as do --verbose installs.
prisma-cli-cause-code: failure.code from Composer's run report, read by passing --report <tmpfile> to prisma deploy. Failed Alchemy children otherwise arrive as the generic CLI.CHILD_PROCESS_FAILED.

Privacy: a value is sent only when it matches its source's identifier grammar at the position that tool prints it. Messages, output, paths and the report's failure.message (which contains local paths) are never read into telemetry. The report lives in a scoped temp directory; a missing or invalid report leaves the deploy and its error untouched. Human and --json output are unchanged.

Output shapes were taken from real failed installs (npm 8/10/11, pnpm 9/10/11, Yarn 1.22/4.18, Bun, Deno); the report shape was checked against composer-cli 0.20.0 and a real failing prisma deploy --report. check, typecheck, unit tests, check:pins and build pass. Not run on Windows; a cloud deploy with a failing Alchemy child is covered only by a fake runner.

#110 is merged. Out of scope: auth login failures. Related: prisma/prisma-cli#276.

🤖 Generated with Claude Code

Install failures carried only an exit code, and deploys whose delegated process failed arrived as the generic CLI.CHILD_PROCESS_FAILED. - Add `package-manager-error-code`: the manager's own identifier read from captured install output (npm `E…`, pnpm `ERR_PNPM_…`/`E…`, Yarn Berry `YN0035`-style). Only values matching the manager's identifier grammar are emitted; Bun, Deno and Yarn Classic print prose, so they report null. - Pass `--report <file>` to `prisma deploy` using a scoped temporary directory, decode the run report, and carry its `failure.code` on PrismaCliCommandError as `causeCode`. Send it as `prisma-cli-cause-code` when it matches the structured-code grammar. A missing or invalid report leaves the original error untouched. Messages, paths, package names and command output are never sent. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Summary by CodeRabbit

New Features
- Deployment failures can now include structured diagnostic codes from Composer reports.
- Telemetry captures sanitized package-manager and deployment error codes when available, making failures easier to identify without collecting messages or command output.
- Error-code detection supports npm, pnpm, and Yarn output while filtering invalid or sensitive values.
Documentation
- Updated telemetry documentation to clarify that failure events contain stable identifiers only, such as exit codes and tool error codes.

Walkthrough

The change adds structured error-code validation and package-manager error-code extraction. Composer deployments can write and parse scoped diagnostic reports, then attach valid failure codes to Prisma CLI errors. Deployment execution uses the new Composer effect. Failure telemetry records validated Prisma cause codes and package-manager codes for dependency-install failures. Documentation and tests were updated.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to de9ba

Telemetry may include a malformed identifier with a trailing newline; tighten validation before merging.

Only npm was checked before writing project files. A pnpm, Yarn, Bun, or Deno that was missing or unusable was discovered when `<pm> install` failed inside an already scaffolded project, and recorded as a dependency_install_failed technical failure. verifyPackageManagerEffect now probes every manager's version through CommandRunner with one shared version parser: - A missing manager is rejected as package_manager_not_found at validate_input, an expected rejection, with install guidance. - Yarn 1 is rejected as unsupported_package_manager_version. It exits with an error in a project whose "packageManager" names Yarn 4. npm keeps its 11.6.0 minimum. pnpm, Bun, and Deno get no minimum because nothing in the repo shows an older release failing. - Any other probe failure, including unreadable version output or a probe directory that cannot be created, is package_manager_check_failed at validate_input instead of dependency_install_failed. The version a manager reports depends on the directory. Corepack's yarn is Yarn 1 outside a project and the pinned release inside one, and pnpm and Corepack refuse to run where "packageManager" names another tool. Only the generated project's manifest decides what the install will run, so the probe always runs in a scoped temporary directory holding a package.json with the generated project's "packageManager" value (none for Deno), and never in the working directory. On Windows execa runs non-.exe commands through cmd.exe, so a missing manager exits non-zero and never raises ENOENT. CommandRunner now resolves the command the way cross-spawn does (working directory, PATH, PATHEXT) and classifies an unresolvable failed command as command_not_found, without reading cmd.exe's localized output.
