This is because by default, you cannot keep references to request data beyond the scope of the handler. What you're seeing is that the underlying buffer of the string is reused between requests.
See the fine print at the end of the BodyParser section: https://docs.gofiber.io/api/ctx#bodyparser
Please note that other methods have this same behavior.

You can get around this two ways:

• Use the Immutable config setting https://docs.gofiber.io/api/fiber#config . You most likely will never notice the performance hit from enabling this (depending on what you're doing, of course).
• Make a copy of the data, eg record.Value = strings.Clone(record.Value). Unfortunately, there isn't a super simple way to make a deep copy of a struct. You'd need to manually copy each string field in your struct.
