Amazon CodeWhisperer Not Working Fix: A Troubleshooting Guide
Is Amazon CodeWhisperer failing to provide suggestions or connect? Don’t let a broken AI coding assistant slow you down.
1. Verify AWS Toolkit and IDE Integration
Often, CodeWhisperer issues stem from an outdated or improperly configured AWS Toolkit extension in your IDE.
Why this happens:
IDE extensions can become corrupted, or new CodeWhisperer features might require a more recent version of the AWS Toolkit. Incompatible IDE versions can also prevent the toolkit from functioning correctly.
How to fix:
- Update AWS Toolkit:
- For VS Code: Go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X), search for "AWS Toolkit," and click "Update" if available.
- For JetBrains IDEs (IntelliJ IDEA, PyCharm, etc.): Go to
File > Settings > Plugins(Windows/Linux) orIntelliJ IDEA > Preferences > Plugins(macOS), find "AWS Toolkit," and update it.
- Restart Your IDE: After updating, always restart your IDE to ensure changes take effect.
- Reinstall AWS Toolkit: If updating doesn’t work, uninstall the AWS Toolkit, restart your IDE, then reinstall it from scratch.
- Check IDE Compatibility: Ensure your IDE version is supported by the latest AWS Toolkit. Refer to the official AWS Toolkit documentation for compatibility matrices.
- Disable Conflicting Extensions: Temporarily disable other AI coding assistants or extensions that might conflict with CodeWhisperer (e.g., GitHub Copilot) to rule out interference.
2. Check AWS Credentials and Region Configuration
CodeWhisperer requires active AWS credentials and must be enabled in the region you’re working in.
Why this happens:
Expired sessions, incorrect AWS profiles, or CodeWhisperer not being provisioned in your chosen AWS region can prevent it from working. You might see errors like "CodeWhisperer: Not enabled for current user" if the service isn’t active in your region or for your account.
Diagnostic checklist before you escalate
Agent and coding-assistant failures span model access, repository context, permissions, tool execution, terminal state, and usage limits. Start with a bounded task and a clean workspace. Review every proposed command and diff, especially when the agent can modify files or call external services.
- Confirm the selected model and plan support agent or tool use.
- Open the correct project and refresh its index or repository context.
- Check pending permission prompts, terminal errors, and ignored files.
- Retry with a small task that names the file, desired behavior, and acceptance check.
- Review diffs and tests before accepting changes or allowing destructive commands.
| Test | What the result tells you | Next move |
|---|---|---|
| Official status page reports an incident | The service is affected beyond your device | Pause local resets and monitor recovery |
| Private window works | Normal browser data or an extension is involved | Clear site data and enable extensions one by one |
| Another network works | DNS, VPN, proxy, firewall, or filtering is involved | Review the original network configuration |
| Failure follows the account everywhere | Account, plan, quota, or service-side state is likely | Collect evidence and contact official support |
Verify the agent with a bounded, reversible task
Test Amazon CodeWhisperer Not Working on a small task that has an obvious expected result, such as changing one label, explaining one function, or adding a focused validation check. Give the agent the relevant file and acceptance condition. A healthy run should read the right context, request necessary permission, make only the intended change, and report how it verified the result.
Inspect the complete diff before accepting it. Then run the repository’s formatter, type checker, and focused tests yourself. If the agent claims success without a diff or test evidence, treat the task as incomplete. Only after this bounded test should you allow broader edits, terminal commands, package changes, or access to external services.
- The agent uses the intended repository and files.
- Permission prompts appear before consequential actions.
- The diff is limited to the requested behavior.
- Tests and type checks pass independently.
- Reverting the test change is straightforward.
Keep a short note of the working configuration and the date of the test. Products, models, browser versions, limits, and safety policies change over time, so a previously successful workaround may later become obsolete. Prefer current official documentation over old forum instructions, and reverse temporary diagnostic changes once testing is complete. This gives you a reliable baseline without leaving extensions disabled, security controls weakened, or experimental settings enabled indefinitely. Recheck the baseline after major updates before assuming an older failure has returned for the same reason.
When none of the fixes work
Repeat the smallest failing action once and record the exact local time and time zone. Note the product, model or feature, account plan, browser or app version, operating system, and whether the same action works in a private window, on another device, or on another network. This evidence is much more useful than saying the tool is “still broken.”
Use the provider’s official support channel. Include a screenshot with sensitive information removed and list the steps already tested. For developer tools, add sanitized request and response details, correlation IDs, and SDK versions. Never send passwords, one-time codes, API keys, session cookies, private repository contents, or complete payment information.
Frequently asked questions
Should I reinstall the app immediately?
No. Check service status, session, browser, and network first. Reinstall only when the failure is isolated to the installed app.
What should I send to support?
Include the exact error, timestamp and time zone, device, browser or app version, and the troubleshooting steps already tested. Remove secrets and personal data.
Bottom line: Work from the least disruptive test to the most specific one. Confirm service health, isolate session and network variables, then escalate with clean evidence instead of repeating the same failing action.
