When you encounter the error “TypeError: Cannot read properties of undefined (reading ‘pipe’)”, it usually means that you are trying to access the property ‘pipe’ of an object that is undefined.
To understand this error better, let’s see an example:
// Example 1
let x;
let y = x.pipe(); // This will throw a TypeError, as 'x' is undefined
In the above example, ‘x’ is undefined, and you are trying to access the ‘pipe’ property on it. This will throw a TypeError because undefined does not have a ‘pipe’ property.
To fix this error, you need to ensure that the object is defined before accessing its properties. Here’s an updated example:
// Example 2
let x = someObject; // 'someObject' is defined
let y = x.pipe(); // Now 'x' is a defined object and you can access its properties
In the above example, ‘x’ is set to a defined object (‘someObject’) before accessing the ‘pipe’ property. This will prevent the TypeError.
