object of class symfony\component\form\formview could not be converted to string

The error message "Object of class Symfony\Component\Form\FormView could not be converted to string" suggests that you are trying to convert an object of the class Symfony\Component\Form\FormView into a string, which is not possible.

To resolve this issue, you need to determine where in your code this conversion is happening and modify it accordingly. It's important to note that the specific solution may depend on the context in which this error is occurring. However, here are a few general suggestions that might help:

1. Check the variable or expression you are trying to convert to a string. Make sure it is indeed an instance of Symfony\Component\Form\FormView.

2. If you are trying to output or display the object as a string, you can use the var_dump() or print_r() functions to get more information about the object and its properties.

3. If you are using the object in a string concatenation, make sure to access the appropriate property or method of the object that provides the desired string representation.

4. If you are trying to pass the object as an argument to a function or method that expects a string, you might need to modify the function or method to accept the FormView object directly or extract the necessary information from the object to use it in the desired way.

Remember, these are general suggestions, and the specific solution will depend on your code and the context in which the error is occurring.
