Troubleshooting

Duplicate Action Error

Duplicate Action Error

If you define multiple actions with the same name and object type, INGenious will report a duplicate action error during plugin loading and the application will exit. Ensure that each action method within an object type has a unique name to avoid this issue.

Below is an example of the error you might encounter:

    Duplicate action 'assertOddNumberDataSheet' for object type 'Numeric Assert' detected:
    - Original found in: text-assertion-plugin (class: com.ing.plugin2.Plugin2)
    - Duplicate found in: sample-plugin (class: com.ing.plugin.cloader.PluginCloader)
    Duplicate action 'GetOccurence' for object type 'String Operations' detected:
    - Original found in: core (class: com.ing.engine.commands.stringOperations.StringOperations)
    - Duplicate found in: sample-plugin (class: com.ing.plugin.cloader.PluginCloader)
    Duplicate method names detected in the loaded actions. Please resolve the conflicts.
ClassCastException Error

If you encounter a ClassCastException when casting Playwright objects, check the following:

  1. Dependency Scope: Ensure Playwright dependency uses <scope>provided</scope> in your pom.xml
  2. Correct Type: Verify you're casting to the correct Playwright type
  3. Null Check: Always check if the object is null before casting
// ✅ Correct pattern
Page page = (Page) getPage();
if (page != null) {
    page.navigate("https://example.com");
}

// ❌ Wrong - missing null check
Page page = (Page) getPage();
page.navigate("https://example.com"); // NullPointerException if null
Java Version Error (UnsupportedClassVersionError)

If you see an error like:

java.lang.UnsupportedClassVersionError: 
com/example/plugin/MyAction has been compiled by a more recent version of the Java Runtime

Cause: You are using a plugin that was compiled with a newer Java version than your machine's JVM supports.

Solution: Upgrade machine's JRE.

NoSuchMethodError

If you encounter NoSuchMethodError at runtime:

java.lang.NoSuchMethodError: com.microsoft.playwright.Page.someNewMethod()

Cause: Your plugin is trying to use a Playwright API method that doesn't exist in the framework's Playwright version.

Solution: 1. Check the framework's Playwright version (currently 1.50.0) 2. Update your plugin's Playwright dependency to match:

<dependency>
    <groupId>com.microsoft.playwright</groupId>
    <artifactId>playwright</artifactId>
    <version>1.50.0</version>
    <scope>provided</scope>
</dependency>
  1. Use only APIs available in Playwright 1.50.0
NoClassDefFoundError for Playwright Classes

If you see:

java.lang.NoClassDefFoundError: com/microsoft/playwright/Page

Cause: Missing Playwright dependency in your plugin's pom.xml.

Solution: Add Playwright dependency with provided scope (see Step 1 of How to Create Your Plugin).
