Error message
TypeError: Cannot read properties of undefined (reading 'replace')
What broke
The code attempted to access a property or method on a variable that is currently undefined. This typically happens when the variable was not initialized or assigned a value before being used.
Why it broke
It broke because the variable expected to hold a string (or similar object) is actually undefined at the time the 'replace' method is called. This can occur due to a missing assignment or an error in data retrieval.
How to fix
To fix this, ensure that the variable is properly initialized with a string value before calling the 'replace' method. You can also add a check to confirm the variable is defined before using it.
