Exception on event handler for event beforeShowContent DUPLICATED_CONTEXT_PROPERTY: Duplicated propertyName. Trying to add more than one extra context property with the same name. what's the cause and solution of the error ?

AI generated answer (using internal Slack threads):

The error 'Exception on event handler for event beforeShowContent DUPLICATED_CONTEXT_PROPERTY: Duplicated propertyName. Trying to add more than one extra context property with the same name' is caused when you're trying to add more than one extra context property with the same name in your SuiteScript. In NetSuite, context properties are used to pass additional information to event handlers. If you try to add more than one property with the same name, NetSuite will throw this error because it expects each property to have a unique name. To resolve this issue, you should ensure that each extra context property you add has a unique name. If you're adding these properties in a loop or some other form of repetitive code, consider appending a unique identifier (like an index or timestamp) to each property name to ensure uniqueness. Here's a simple example of how you might do this:

javascript
for (var i = 0; i < someArray.length; i++) {
    context.addProperty('propertyName' + i, someArray[i]);
}

In this example, each property added to the context will have a unique name ('propertyName0', 'propertyName1', etc.), which should prevent the DUPLICATED_CONTEXT_PROPERTY error. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
