Create a mutable global variable in M language
Hi, community, I'm working on a custom connector that needs to authenticate before data representation is done, and to do this I don't want to hardcode the auth credentials in my source code. So, I declared a global list variable named config = {"a"}; and in the shared MyCustomConnector.Contents function, I'm doing a List.ReplaceValue on item "a" in the list above. shared MyCustomConnector.Contents = (BaseUrl as text, ClientId as text) => List.ReplaceValue(config, "a", BaseUrl, Replacer.ReplaceText); so in my StartLogin function, I can just call the config by index like this. //Start Login StartLogin = (resourceUrl, state, display) => let AuthorizeUrl ="https://"&Text.From(config{0})&"/oauth/authorize?" & Uri.BuildQueryString( [ client_id = "11", response_type="code", state = state, redirect_uri = redirect_uri ] ) in [ LoginUri = AuthorizeUrl, CallbackUri = redirect_uri, WindowHeight = windowHeight, WindowWidth = windowWidth, Context = null ]; But it appears that, the List.ReplaceValue is not being executed because whenever I try to set credential for authentication, "a" is being passed into the URL. Any help will be much appreciated
