    2. Rename Variables: If you have control over the code, rename any variables or fields that do not comply with the naming conventions.
    3. Review Code: If the error occurs in a larger piece of code, check all identifiers in the relevant scope to ensure they conform to the naming rules.
    4. Use Descriptive Names: When renaming, use descriptive names that reflect the purpose of the variable or field, which can help improve code readability.
