func myHandler(ctx *context.Context) { if ctx.HasError() { ctx.JSON(500, map[string]interface{}{ "error": "An error occurred", }) return } // Your code here }In this example, the `HasError` function is called on the `ctx` object to check for any errors. If an error occurred, a JSON response with the status code 500 is returned. If no errors occurred, the code continues to execute normally. Overall, the Gogs module in Go provides developers with powerful tools for building web applications. This middleware in particular, is essential for handling errors and improving overall software reliability.
