update view is not working

[irania30]

in view_submission i want to update view by using this function NewUpdateViewSubmissionResponse, but always get error. how to fix it?

resp := slack.NewUpdateViewSubmissionResponse(modal) respByte, _ = json.Marshal(resp)

w.WriteHeader(http.StatusOK) w.Header.Add("Content-Type", "application/json") w.Write(respByte)

Please give reproducible code, slack-go's version, Go's version.

Is there any chance to use UpdateView instead? When I want to update an existing view it worked fine for me.

[irania30]

i have tried that function, but it only works in block_action type

but i'll try again, anyway what version do you use @KouWakai ?

[KouWakai]

mines are: github.com/slack-go/slack v0.11.4 go version go1.19.3

[KouWakai]

@irania30 According to https://pkg.go.dev/net/http#ResponseWriter We need to set any HTTP Trailers before writing.

With this order,it worked as expected.

w.Header().Add("Content-Type", "application/json")
w.WriteHeader(http.StatusOK)
w.Write(respByte)

version: github.com/slack-go/slack v0.11.3 go version go1.19.3

[irania30]

ok, i'll try again

[irania30]

nice, it works now, thank you @KouWakai
