Error Message: “elem._marshal is not a function”
This error typically occurs when a script expects a certain data type (e.g., a string or a single value) but receives a different type (e.g., an object or an array).
Common Scenario
This error can happen while using the search.create function in NetSuite. It occurs when a parameter expecting a single internal ID value is provided with an object or any other data type other than the expected.
Example Scenario
When executing the following script:
var searchResult = search.create({
type: search.Type.CUSTOMER,
filters: [
[‘internalid’, ‘anyof’, { id: 123 }]
],
columns: [‘entityid’, ’email’]
}).run().getRange({ start: 0, end: 10 });
You might encounter the “elem._marshal is not a function” error because an object is passed instead of a single value.
Solution
To resolve this error, ensure that the data type of the parameters matches the expected type by the function. In the given example, replace the object with the internal ID as a single value:
var searchResult = search.create({
type: search.Type.CUSTOMER,
filters: [
[‘internalid’, ‘anyof’, 123]
],
columns: [‘entityid’, ’email’]
}).run().getRange({ start: 0, end: 10 });
This modification passes the internal ID directly instead of wrapping it in an object, thus aligning with the expected input format for the search.create function.
