This error message typically occurs when defining a function in an invalid location within the code. It usually indicates that there is a syntax error in the code, such as a missing or misplaced bracket or parenthesis.
To fix this error, check the location of the function definition and ensure that it is within the appropriate scope and syntax. Make sure that all brackets and parentheses are properly balanced and that there are no extra or missing ones. Also, check for any other syntax errors in the code.
