我试图将我的 Go 应用程序部署到 App Engine。我有以下构建错误：

我的 app.yaml 文件如下所示：

我在根目录下的 main.go 文件如下所示：
package main

client, err := getNewFirestoreClient(ctx)
writeLogIfError(c, err)
defer client.Close()
// Get form data
var form formData
c.BindJSON(&form)
// [START add user to firestore]

// [END add user to firestore]
c.JSON(http.StatusOK, gin.H{"status": "user added to db"})
}
如果没有这些构建错误，我将无法成功构建。我试图完全按照 Go on App Engine 的文档进行操作，如果我的应用程序结构与建议的不同，我会感到困惑。关于如何解决此 GOPATH 错误的任何想法？
