Error message
TypeError: Cannot read properties of undefined (reading 'params')
What broke
The code attempted to read the 'params' property from an object that is currently undefined. This often happens when an expected object is not properly initialized or passed to a function.
Why it broke
It broke because the variable or object you're trying to access has not been defined or assigned a value before you attempt to read its properties. This can occur due to incorrect function arguments or missing data.
How to fix
To fix this, ensure that the object you're trying to access is defined before you attempt to read its properties. You can add checks to confirm the object exists or provide default values.
Code fix
if (obj && obj.params) { /* your code here */ }Explained by ErrorOracle
Prevention tip
You can add checks to confirm the object exists or provide default values.
