Error in callback for watcher "sunInputsBool": "TypeError: Cannot read properties of undefined (reading 'form')"

As an AI language model, I cannot provide a specific solution without more context on the code and the error. However, this error message suggests that there is an issue with the code that is trying to access a property of an undefined variable.

One possibility is that the variable "form" is not defined or has not been initialized before it is being accessed in the code. Check if the variable is being properly declared and initialized before using it in the code.

Another possibility is that there is a typo or a syntax error in the code that is preventing the variable from being defined or accessed properly. Double-check the code for any errors in spelling or syntax that could be causing this issue.

It would be helpful to provide more information and context on the code to get a more specific answer.
