fix: surface 429 rate-limit errors in e2e tests and CLI#1309
Merged
Conversation
Multiple layered issues caused encryption key 429 errors to produce
confusing, unrelated-looking test failures:
- awaitCommand() in e2e utils now rejects on non-zero exit codes
instead of silently resolving (the most critical fix)
- cliInspectJson/cliHealthJson throw on empty stdout instead of
falling back to '{}'
- maybeDecryptFields re-throws HTTP errors instead of silently
falling back to encrypted placeholders
- fetchRunKey includes response body and status text in errors
- Added 429 to CLI status text map

Pull request overview
This PR improves error surfacing for HTTP failures (especially 429 rate-limit errors) across the e2e test suite, CLI hydration layer, and Vercel encryption key fetch. Previously, rate-limit responses would produce confusing, unrelated test failures with misleading assertion errors. The fix addresses four stacked issues: silent exit code handling in tests, empty stdout fallback, swallowed HTTP errors during decryption, and generic error messages in fetchRunKey.
Changes:
awaitCommand()now rejects on non-zero exit codes (with stderr/stdout in the error), andcliInspectJson()/cliHealthJson()throw on empty stdout instead of silently parsing{}.maybeDecryptFields()re-throws HTTP errors instead of falling back to encrypted placeholders, andfetchRunKey()now includes response body and status text in error messages.- Added
429: 'Too Many Requests'to the CLI'sgetStatusText()map.

There was a problem hiding this comment.
The message.includes('HTTP ') heuristic for distinguishing HTTP errors from decryption errors is fragile. If any future error message from maybeDecrypt, importKey, or other code in the try block happens to contain the substring "HTTP ", it will be incorrectly re-thrown instead of falling through to the graceful fallback.
Consider a more robust approach, such as checking for the specific prefix used in fetchRunKey (e.g., message.startsWith('Failed to fetch run key')) or tagging HTTP errors with a custom property (e.g., error.isHttpError = true) in fetchRunKey and checking for that property here.
Suggested change

| (err as any)?.isHttpError === true || | |
| message.startsWith('Failed to fetch run key'); | |
| if (isHttpError) { |

Summary
Problem
When the Vercel run-key endpoint returns a 429, the test failures show misleading assertion errors like
expected 133, received "🔒 Encrypted"with no indication of the actual cause. This is due to 4 stacked issues:awaitCommand()ignores exit codes (packages/core/e2e/utils.ts) — always resolves even when the CLI exits with code 1cliInspectJson()falls back to{}on empty stdout — silently parses to an empty objectmaybeDecryptFields()swallows HTTP errors (packages/cli/src/lib/inspect/hydration.ts) — catches 429 errors and silently falls back to encrypted placeholdersfetchRunKey()produces generic error messages (packages/world-vercel/src/encryption.ts) — drops the response body and status textChanges
