Missing timeout: TypeScript SDK server-manager — waitForServer() health check fetch

[realfishsam]

Location

sdks/typescript/pmxt/server-manager.ts:132

Code

// waitForServer() retry loop
for (let i = 0; i < this.maxRetries; i++) {
    const info = this.getServerInfo();
    if (info) {
        try {
            const response = await fetch(`http://localhost:${info.port}/health`);

Risk

Inside waitForServer(), the health check fetch has no timeout. Each iteration of the retry loop can hang indefinitely before the retry count is checked. If the sidecar process is unresponsive (not crashing, just hung), the total wait is unbounded regardless of maxRetries.

Affected Methods

• ServerManager.waitForServer() — called during ensureServerRunning() which gates all SDK operations

Suggested Fix

const response = await fetch(`http://localhost:${info.port}/health`, {
    signal: AbortSignal.timeout(5_000),
});
