What is TypeError: Cannot read properties of undefined (reading 'product')?

AI generated answer (using internal Slack threads):

The error

TypeError: Cannot read properties of undefined (reading 'product')

typically occurs in JavaScript when you try to access a property of an object that is

undefined

. This means that the object you're trying to access the property from does not exist or has not been initialized. In the context of SuiteScript, this error could occur if you're trying to access a field or property from a record or search result that does not exist or has not been loaded correctly. For example, if you have a line of code like this:

var productName = record.product;

and

record

is undefined, you would get the error

TypeError: Cannot read properties of undefined (reading 'product')

. To avoid this error, you should always ensure that the object you're trying to access a property from is defined and not null. You can do this by adding a check before accessing the property. For example:

javascript
if (record) {
    var productName = record.product;
}

In this case, the

productName

variable will only be assigned if

record

is defined. If

record

is undefined, the code inside the if statement will not be executed, and you will avoid the TypeError. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
