Hello! As a seasoned software engineer, I can help you with your question.
The error message “golang must be a constant expression” usually occurs when trying to use a non-constant value as a parameter in certain Go functions or declarations that require constants. In other words, the value being used needs to be known at compile-time.
To solve this issue, you can use const declaration for the value or variable being used and ensure that it’s assigned a value that is known at compile-time. Alternatively, you can use expressions that are guaranteed to be constant at runtime.
I hope this helps! Let me know if you have any further questions or concerns.
