This error message is indicating that you are trying to access the property ‘transformfile’ of an undefined object. In other words, the variable you are trying to access doesn’t have the expected value or doesn’t exist at all.
To fix this error, you need to ensure that the variable you are accessing is properly defined and has the necessary properties.
Example 1:
let obj; // obj is undefined
console.log(obj.transformfile); // Error: Cannot read properties of undefined (reading 'transformfile')
In the above example, the variable ‘obj’ is not assigned any value, so it is ‘undefined’. When we try to access the ‘transformfile’ property of ‘obj’, it throws a TypeError because undefined doesn’t have any properties.
Example 2:
let obj = { transformfile: 'example.js' }; // obj is defined with a property
console.log(obj.transformfile); // 'example.js'
In this example, the variable ‘obj’ is defined as an object with a ‘transformfile’ property. When we access the ‘transformfile’ property of ‘obj’, it returns the expected value ‘example.js’ without throwing any errors.
