${argv[0]} exited with code ${exitCode}: ${stderr.trim().sli

Error message

${argv[0]} exited with code ${exitCode}: ${stderr.trim().slice(-300)}

What it means

The command uploader spawns the configured upload program and captures stdout, stderr, and the exit code. If the program exits with a nonzero code, the error surfaces the program name, exit code, and the last 300 characters of stderr. This propagates the external tool's own failure rather than hiding it.

/**
 * Resolve one registry destination to its built-in uploader.
 *
 * Serving destinations deliberately return `null`; the broker selects those
 * through its separate serve-kind predicate. Registry entries known to be
 * unusable, and active entries without an implementation, fail explicitly
 * before an upload can issue a network request.

Solutions

1. Read the stderr tail in the error message — it contains the tool's own diagnostic
2. Run the command manually with a test file, substituting the path for {file}, to reproduce
3. Check/rotate credentials or tokens for the upload service
4. Increase headroom for the timeout (upload smaller files / faster network) or verify flag syntax after placeholder substitution

Example fix

// before
"urls": { "command": "curl -F file={file} https://0x0.st" }  // shell parses {file} oddly
// after
"urls": { "command": "curl -sF 'file=@{file}' https://0x0.st" }

// dry-run the command template before wiring it:
const argv = template.split(" ").map(a => a.replaceAll("{file}", "/tmp/test.png"));
const proc = Bun.spawn(argv, { stdout: "pipe", stderr: "pipe" });
if ((await proc.exited) !== 0) console.error("upload command fails outside the broker too");

try {
	await uploader.upload(req);
} catch (err) {
	if (err instanceof Error && /exited with code/.test(err.message)) {
		// read the stderr tail embedded in the message for the tool's own diagnostic
	}
	throw err;
}

When it happens

Trigger: The configured images.urls.command program fails for any reason: bad credentials, network failure, invalid flags (often because {file}/{mime}/{ext} substitution produces an unexpected argument), server rejection of the upload (4xx/5xx), or the program being killed by UPLOAD_TIMEOUT_MS timeout (proc.kill).

Common situations: Expired or wrong upload-service API token; the placeholder-substituted arguments don't match the tool's CLI syntax; rate limiting or file-size limits on the target service; a slow network hitting the upload timeout and killing the process.
