Cannot use cors default as type gin.HandlerFunc in argument to router.Use about cors

[RCM7]

did you import cors "github.com/rs/cors/wrapper/gin" ?
Also, would really help if you put the snippet with markdown code...

The error is -

cannot use "github.com/rs/cors/wrapper/gin".AllowAll() (type "github.com/gin-gonic/gin".HandlerFunc) as type "github.com/<your workspace>/vendor/github.com/gin-gonic/gin".HandlerFunc in argument to router.Use

This is due to your dependencies not being updated

go get -u github.com/rs/cors/wrapper/gin

godep save

and this should fix the above issue

Yes I did.

r := gin.Default()
r.Use(cors.Default())
v1 := r.Group("/v1")
{
item := v1.Group("/item")
{
item.POST("/new", controllers.AddItem)
item.GET("/", controllers.GetAllItems)
item.GET("/:id", controllers.GetItem)
item.PUT("/update", controllers.UpdateItem)
item.DELETE("/", controllers.DeleteItem)
}
verify := v1.Group("/verify")
{
verify.POST("/", controllers.VerifyItem)
}
}
return r

Please include the imports you are using in your snippet.

@emmanuelbenson did you try putting:

r.Use(cors.Default())

to the last (before return):

r.Use(cors.Default())
return r

This is likely due to no OPTIONS routes defined for the router, gin will just return 404. But if we put the cors into the bottom (i.e. the last one in the router middleware stack), it will catch all unhandled request (and generate a cors response).
