fix(api): reject an invalid request body locally - #464
Conversation
`clerk api -d` / `--file` / piped stdin forwarded the body verbatim with
`Content-Type: application/json`, so an unparseable payload only failed at
the API, a round trip later, and showed up server-side as a JSON decode
error. Parse-check the body before it goes out and fail as a usage error
that echoes what actually arrived.
A `-d` value is the one body that crosses the shell as an argument, and two
mangled shapes give the cause away: every double quote stripped (an unquoted
body in a POSIX shell; PowerShell before 7.3 or cmd.exe on Windows even with
quotes), or the body still wrapped in literal single quotes (cmd.exe). Those
are diagnosed per platform, with a runnable suggestion that repeats the
caller's own targeting flags, and reported under a distinct
`invalid_json_shell_quoting` code so they can be counted apart from ordinary
typos. Bodies from a file or a pipe never went through argument parsing and
get no shell blame, and Python-style `{'a': 'b'}` falls through to the
parser's own message.

Looks good. The validation stays scoped to raw clerk api bodies, preserves valid payloads byte-for-byte, avoids blaming file/stdin input on shell quoting, and keeps secret keys out of generated examples. Coverage includes the Windows/POSIX diagnoses, source-specific failures, no-request behavior, dry-run, targeting flags, and ordinary malformed JSON. Build, unit tests, lint, typecheck, and changeset checks are green; E2E is still running.

- Line 195: Update the request-body handling around validateJsonBody to detect
explicitly supplied data by source presence rather than truthiness, so -d "" is
validated and reports INVALID_JSON. When stdin is piped, always pass its
original untrimmed contents to validateJsonBody, including empty or
whitespace-only input, and preserve the existing bodyless-request path only when
no body source was supplied.
In `@packages/cli-core/src/commands/users/README.md`:
- Line 97: Update the Windows-shell warning in the users README to state that
the -d '{"…"}' form can fail specifically in PowerShell versions before 7.3 and
in cmd.exe, rather than broadly referring to all Windows shells.
In `@packages/cli-core/src/lib/json-body.ts`:
- Line 88: Update the recovery-command construction around the
parts.push(request.endpoint) call to shell-quote or escape request.endpoint,
app, and instance before insertion, preserving their exact values when executed
by the target shell. Add a regression test covering a query-string endpoint such
as /users?limit=1&offset=20.

Address the second round of CodeRabbit review on the local JSON body check. - Shell-quote the endpoint, method, --app, and --instance in the suggested recovery command, so `/users?limit=1&offset=20` survives as one word instead of a backgrounded command and a glob. Plain paths and identifiers stay bare. Windows gets double quotes, POSIX single quotes. - Detect `-d` by presence, not truthiness: an explicit `-d ""` is an empty body to reject, not a request with no body. - Forward a piped body untrimmed, like a --file body. An empty non-TTY stdin still means no body, since CI, cron, and `< /dev/null` all look like a pipe carrying nothing and a plain GET must keep working there. - Name the affected shells in the READMEs (cmd.exe and PowerShell before 7.3) instead of claiming the form fails in every Windows shell.

Reject a whitespace-only piped body.
text.trim() treats a nonempty whitespace-only pipe as absent. printf ' \n' | clerk api /users then bypasses validateJsonBody and sends a bodyless GET request. Treat only text.length === 0 as absent. Validate every nonempty stdin payload.

Generate separate PowerShell-safe recovery commands.
When process.platform === "win32", apiCommand passes the endpoint to quoteArg, which emits double quotes. PowerShell expands $ in those quotes, so an endpoint such as /users?$limit=1 can change before clerk receives it. Emit separate cmd.exe and PowerShell forms with PowerShell single-quote escaping.

In PowerShell 7.2 or older,
clerk api /users -d '{"first_name":"Alice"}'reaches the CLI as{first_name:Alice}. Before this change that body went to the API and came back as a server-side decode error. Now it fails locally, with exit code 2:On macOS and Linux the same shape means the user left off the single quotes, so the message says to add them and the first suggestion is
clerk api /users -d '{"key":"value"}'. In agent mode the failure is the usual JSON error object, withcodeset toinvalid_json_shell_quotingand the suggested command underexamples.Linear: AIE-1650 https://linear.app/clerk/issue/AIE-1650/handle-invalid-json-escaping-on-windows
