When encountering the `Function deploy failed due to an internal error`, try deploy the function via the [Supabase CLI](/docs/guides/local-development) with the `--debug` flag to gather extra information to identify the possible cause.

You can also try [alternative bundle methods](/docs/reference/cli/supabase-functions-deploy):

- `--use-api`: Use Management API to bundle functions.
- `--use-docker`: Use Docker to bundle functions.

If you're not able to run the CLI or cannot identify the cause, [open a support ticket](/dashboard/support/new).

**Example error**

```
$ supabase functions deploy FUNCTION_NAME --project-ref $PROJECT_ID
...
unexpected deploy status 500: {"message":"Function deploy failed due to an internal error"}
```

**Example output with `--debug`**

- From the details we can see it is exceeding the 20MB [Edge Function size limit](/docs/guides/functions/limits)

```
$ supabase functions deploy FUNCTION_NAME --project-ref $PROJECT_ID --debug
...
Deploying Function: FUNCTION_NAME (script size: 62.61MB)
...
unexpected update function status 413: {"message":"request entity too large"}
