# Troubleshoot Snippets

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/errors/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

## Error 1201: Snippet tried to continue to origin multiple times

This error occurs when a Snippet attempts to call `fetch(request)` more than once.

### Resolution

Ensure that your Snippet code only calls `fetch(request)` once. This method is used to send the modified request to the origin server, and it should be called only once per Snippet to avoid conflicts.

## Error 1202: Snippets exceeded subrequests limit

This error occurs when the number of subrequests exceeds [the limit](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/#availability) for your Cloudflare plan.

### Resolution

Review your Snippet to ensure your code is within the subrequest [limits](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/#availability) for your plan. Each subrequest counts against your limit, including any redirects within a subrequest chain.

## Error 1203: Snippets exceeded CPU time limit

This error occurs when a Snippet exceeds the defined [CPU time limit](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/#limits) for Snippets.

### Resolution

Review your Snippet to ensure your code is within the CPU time limit. If you need a higher CPU time limit, consider using [Cloudflare Workers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/). Refer to [When to use Snippets vs Workers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/when-to-use/) for details.

## Error 1204: Snippets exceeded memory limit

This error occurs when a Snippet exceeds the defined [memory limit](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/#limits) for Snippets.

### Resolution

Review your Snippet to ensure your code is within the memory limit. If you need a higher memory limit, consider using [Cloudflare Workers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/). Refer to [When to use Snippets vs Workers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/snippets/when-to-use/) for details.

## Error 1205: Deployment in progress

A new Snippet was just deployed and is currently propagating across Cloudflare's global network. During this short window, requests may not be processed as expected.

### Resolution

This is a temporary issue. Retry your request after a few seconds — the Snippet will be active once propagation completes.

## Error 1206: Snippet threw exception

The Snippet encountered an unhandled JavaScript exception during execution. This may be caused by one of the following:

* Runtime JavaScript errors in Snippet code
* Unhandled promise rejections
* Type errors or reference errors

### Resolution

* Review the Snippet code to identify where the exception might have occurred and fix any detected bugs.
* Add proper error handling ([try...catch ↗](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/try...catch) blocks).

## Snippets cannot be renamed

The name you define when creating a Snippet will be used as the Snippet ID and cannot be edited afterwards.

### Resolution

To change the name of your Snippet, create a new Snippet and delete the old one.
