Common Syntax Errors in User Event Scripts

1. Invalid Context Object**

– **Error**: `INVALID_CONTEXT_OBJECT`

– **Example**:

 “`javascript

 define([‘N/record’], function(record) {

   function beforeSubmit(context) {

     var newRecord = context.newRecord;

     newRecord.setValue({

       fieldId: ‘companyname’,

       value: ‘Updated Customer’

     });

   }

   return {

     beforeSubmit: beforeSubmit

   };

 });

 “`

 – **Solution**: Ensure the context object is correctly used and contains the expected properties.

 **Fixed Code Line**:

 “`javascript

 var newRecord = context.newRecord;

 “`

**2. Missing Script Type**

– **Error**: `MISSING_SCRIPT_TYPE`

– **Example**:

 “`javascript

 /**

  * @NApiVersion 2.x

  */

 define([‘N/record’], function(record) {

   function beforeSubmit(context) {

     // User event logic here

   }

   return {

     beforeSubmit: beforeSubmit

   };

 });

 “`

 – **Solution**: Add the `@NScriptType` JSDoc tag to specify the script type.

 **Fixed Code Line**:

 “`javascript

 * @NScriptType UserEventScript

 “`

3. Unexpected Token

Error: SyntaxError: Unexpected token

Example:

define([‘N/record’], function(record) {

  function beforeSubmit(context) {

    var newRecord = context.newRecord;

    newRecord.setValue({

      fieldId: ‘companyname’,

      value: ‘Updated Customer’

    });

  }

  return {

    beforeSubmit: beforeSubmit

  };

});

Solution: Check for missing or extra characters, such as commas, brackets, or parentheses.

Fixed Code Line:

newRecord.setValue({

The error in this example is not immediately obvious because the code snippet provided is actually correct. The issue might arise from a different part of the script or from a missing or extra character elsewhere in the script. Here’s a more detailed explanation:

Possible Error Source: The SyntaxError: Unexpected token can occur if there is a missing or extra character, such as a comma, bracket, or parenthesis, somewhere in the script. This error message indicates that the JavaScript engine encountered a character it didn’t expect while parsing the script.

To help you better, here’s a more comprehensive example with a deliberate syntax error and its fix:

Example with Error:

define([‘N/record’], function(record) {

  function beforeSubmit(context) {

    var newRecord = context.newRecord;

    newRecord.setValue({

      fieldId: ‘companyname’,

      value: ‘Updated Customer’

    }); // Missing closing parenthesis for define function

  }

  return {

    beforeSubmit: beforeSubmit

  };

Fixed Example:

define([‘N/record’], function(record) { // Corrected line

  function beforeSubmit(context) {

    var newRecord = context.newRecord;

    newRecord.setValue({

      fieldId: ‘companyname’,

      value: ‘Updated Customer’

    });

  }

  return {

    beforeSubmit: beforeSubmit

  };

});

In this corrected example, the missing closing parenthesis for the define function is added, resolving the SyntaxError: Unexpected token.
