While attempting to push data, why does the error message state that an argument defined as any cannot be assigned to a parameter defined as never?

This error message usually occurs when TypeScript or another strongly-typed language is being used. It means that the data type of the argument being passed to the function is broader than the data type of the parameter defined in the function.

In other words, the argument can be of any type (including null, undefined, etc.) while the parameter is defined as never, which means it cannot be assigned any value. This type incompatibility can cause unexpected behavior, so the error message is raised to prevent potential errors from occurring.

To resolve the issue, either the data type of the argument needs to be modified to match the data type of the parameter, or the data type of the parameter needs to be modified to be compatible with the argument type.
