Title: How to Find & Fix the Exact File Causing “DEADLINE_EXCEEDED” / 100% CPU Lock in Apps Builder
Hey everyone,
If your Google AI Studio Apps Builder project is completely frozen, giving “An internal error occurred” or DEADLINE_EXCEEDED timeouts, it means the model accidentally generated an infinite loop or a memory leak in your code. This spikes the sandbox container to 100% CPU Lock.
Since every developer is building a different app, you might not know which exact file is causing this deadlock. You cannot scan your workspace manually because the terminal is dead.
Step 1: Find the Broken File (The Diagnosis Prompt)
To force the AI execution agent to dig into its last crash logs and tell you exactly which file is corrupted (without running a heavy workspace scan that times out), paste this Universal Diagnosis Prompt into the chat:
[CRITICAL EMERGENCY: DIAGNOSIS MODE ONLY]
My workspace/terminal is completely frozen with a DEADLINE_EXCEEDED internal error (100% CPU lock). I cannot read the files manually, and you cannot run full workspace scans without timing out.
To help me break this deadlock, you must immediately access your internal operational memory, agent execution history, or the last error stack traces. Do NOT write any new code or build scripts.
Answer these questions instantly:
1. Which exact file path(s) in this current project triggered the last execution failure or infinite loop?
2. What specific component, React hook, or loop function is causing this CPU freeze?
3. Provide a brief report naming only the affected files so I know exactly where the bug is isolated.
Provide this report immediately using minimal text to avoid hitting another timeout.
Step 2: Kill the Loop and Reset the Container
Once the AI responds and names the specific broken file (for example: src/pages/Dashboard.tsx or components/Chat.json), you must immediately force the model to overwrite that file to break the loop.
Paste this follow-up prompt (Make sure to replace YOUR_BROKEN_FILE_PATH_HERE with the actual path the AI gave you in Step 1):
[CRITICAL SYSTEM COMMAND: BYPASS DEADLINE_EXCEEDED]
I know the environment is currently at 100% CPU lock with a DEADLINE_EXCEEDED error due to the infinite loop.
As the Apps Builder execution agent, you must immediately perform the following emergency actions:
DO NOT try to read or scan the entire workspace directory right now.
DO NOT boot the preview server or runtime process.
Immediately OVERWRITE the content of the problematic file: “YOUR_BROKEN_FILE_PATH_HERE” with a blank component or a simple commented-out placeholder to break the loop.
Kill any hung Node.js, Vite, or background processes running in your sandbox container.
Execute this code-fix directly to free up the CPU. Confirm once the container is stable.
Important Note:
Right after sending the second prompt, if you still see the “Internal Error” banner, click Retry or press F5 to Hard Refresh your browser. Once the container syncs, the loop will be broken, and your Terminal, Preview, and Version Restore button will start working again!
