KUBB_PLUGIN_NOT_FOUND: Plugin not found#

Code: KUBB_PLUGIN_NOT_FOUND
Level: error

A plugin requires another plugin that is not in the config.

What happened#

Some plugins build on others. The query and client generators, for example, need @kubb/plugin-ts for the types they emit. When a plugin declares a dependency that is not registered, Kubb cannot run it. OpenAPI parsing is no longer a plugin dependency in v5: the adapter reads the document, so you never list @kubb/plugin-oas.

How to fix it#

• Add the required plugin to the plugins array, and install it if needed.
• Order does not matter. Kubb sorts plugins so dependencies run first, but the plugin must be present.
• Remove the plugin that depends on it if you do not need it.

Common causes#

• The required plugin is installed but not added to the plugins array.
• The required plugin is missing from package.json entirely.

Example#

import { defineConfig } from 'kubb/config'
import { pluginReactQuery } from '@kubb/plugin-react-query'
// @kubb/plugin-ts is missing, but pluginReactQuery needs it for the generated types

export default defineConfig({
  input: './petstore.yaml',
  output: { path: './src/gen' },
  plugins: [pluginReactQuery()],
})

Example output#

[KUBB_PLUGIN_NOT_FOUND]: Plugin "plugin-ts" is required but not found. Make sure it is included in your Kubb config.
  fix: Add "plugin-ts" to the plugins array in kubb.config.ts, or remove the dependency on it.
