version: 0.24.1 Maybe is because dependency updated? How do you fix undefined properties Cannot be read?The error can be fixed by creating a variable to hold the name of the file. This will fix the error and will not change anything in your application. How do I fix uncaught TypeError in JavaScript?To resolve this issue, ensure that the properties you're trying to access are properly initialized. You can use the optional chaining operator ( ?. ) to avoid the error when trying to access a nested property that might be undefined: console. What does Cannot read properties of undefined reading 0 mean?The “cannot read property of undefined” error can occur when you are trying to access a variable or a property that has not been declared yet. This error can also happen if you try to access an implicit template that has not been loaded yet. What is undefined property error in JavaScript?The JavaScript warning "reference to undefined property" occurs when a script attempted to access an object property which doesn't exist. |
