Troubleshooting and Debugging

This page contains a few tips to help you figure out what's wrong when Scribe seems to be malfunctioning.

Update your version#

First off, try updating your installed Scribe version. Maybe your problem is due to a bug we've fixed in a newer release. You can see a list of releases and major changes on the changelog.

  • To find the exact installed version, run composer show knuckleswtf/scribe
  • To update to the latest version, run composer update knuckleswtf/scribe.
  • To update to a specific version (example: 3.0.1), run composer update knuckleswtf/scribe:3.0.1.

Use --verbose#

By default, Scribe will try to keep going until it processes all routes and generates your docs. If it encounters any problems while processing a route (such as a missing @responseFile or some invalid configuration leading to an exception being thrown), it will output a warning and the exception message, then move on to the next route.

You can turn on debug messages (such as the path Scribe takes in instantiating a model) and full stack traces with the --verbose flag:

php artisan scribe:generate --verbose

Make sure you aren't matching web routes#

Routes defined in Laravel's web.php typically have the web middleware, leading to strange behaviour, so make sure you've correctly specified the routes to be matched in your config file. See this GitHub issue.

Turn on debug mode for your app#

Sometimes you may see a 500 null response shown in the generated examples. This is usually because an error occurred within your application during a response call. The quickest way to debug this is by setting app.debug to true in your response_calls.config section in your scribe.php file.

Alternatively, you can set APP_DEBUG=true in your .env.docs file and run php artisan scribe:generate --env docs.

Clear any cached Laravel config#

Sometimes Laravel caches config files, and this may lead to Scribe failing with an error about a null DocumentationConfig. To fix this, clear the config cache:

php artisan config:clear

Clear previously generated docs#

Sometimes you may run into conflicts if you switch from one output type to another. While we try to prevent this happening, we don't guarantee it. In such cases, please try clearing the old docs generated from your previous run (laravel would be in resources/docs and storage/docs, static would be in public/docs) and then running again. We recommend copying these out to a different location, just to be safe.

Increase the memory#

Generating docs for large APIs can be memory intensive. If you run into memory limits, try running PHP with an increased memory limit (either by updating your CLI php.ini file or using a CLI flag):

php -d memory_limit=1G artisan scribe:generate
