Content Type Troubleshooting

Below are common issues regarding content types and their possible solutions.

I have created a content type but receiving a 404 Not Found response

Ensure you are using the correct endpoint tense

• Collection endpoints use their plural name. e.g. /api/posts
• Single types use the singular name. e.g. /api/homepage

Ensure single content type is published

For single content types if draftAndPublish is enabled the response will return a 404 Not Found if the entity is not published.

Plugin Troubleshooting

Below are common solutions regarding issues with plugins

Settings are not being applied

• plugin settings are in ./config/plugins.js not ./config/plugin.js, see project structure.
• settings are now in a configuration object, see plugin configuration.

The "path" argument must be of type string. Received undefined

• before install delete the lock file.
• after install do a clean rebuild of the admin (remove the .cache and build folders)
