I tried to use <on-error ref="test-error-handler"/> to reference the error handling strategy in the Mule Application. I created new test application using Anypoint Studio v7.17 and I encountered that this element causes compilation errors. Has anyone also encountered such a problem and know how to resolve this?

 

<app.runtime>4.6.2</app.runtime>

<mule.maven.plugin.version>4.2.0</mule.maven.plugin.version>

 

Error Message:

[ERROR] Failed to execute goal org.mule.tools.maven:mule-maven-plugin:4.2.0:process-classes (default-process-classes) on project common-extend-test: Fail to compile: Cannot invoke "org.mule.runtime.ast.api.ComponentParameterAst.getRawValue()" because the return value of "org.mule.runtime.config.internal.validation.AbstractErrorValidation.getErrorTypeParam(org.mule.runtime.ast.api.ComponentAst)" is null -> [Help 1]

    Hi ,

    It looks like there is a reference to a common error handler and another 'on error continue' statement present, which is causing the error. Please remove it.

     

    current inside main flow test-raml-main

    <on-error ref="test-error-handler"/>

    <on-error-continue enableNotifications="true" logException="true" doc:name="On Error Continue" doc:id="4a2c18e6-d4a4-4659-afb3-0108f1074b3c" >

    <logger level="INFO" doc:name="Logger" doc:id="318a7585-7926-4dc6-b76a-5ffe72f392b2" />

     

    </on-error-continue>

    </error-handler>

     

    instead only have this

    <error-handler ref="test-error-handler" />
