"Database name is null or empty" in experience editor once I click on language version button

Question

We are getting the error once we click on version and the language. This is happening only the first time. The second time I am clicking it is working fine. error is mentioned herewith image Database name is null or empty.

Answer 1

This happens due to the slow initialization of button states of ExperienceEditor, the gallery button requires the URL query string before opening the menu:

define(["sitecore", "/-/speak/v1/ExperienceEditor/ExperienceEditor.js"], function (Sitecore, ExperienceEditor) {
  Sitecore.Commands.OpenSelectLanguageGallery =
  {
    canExecute: function (context) {
      var queryString = "?itemId=" + context.currentContext.itemId +
        "&database=" + context.currentContext.database +
        "&la=" + context.currentContext.language +
        "&vs=" + context.currentContext.version;
      context.button.set("galleryUrlQueryString", queryString);
      return true;
    },
    execute: function (context) {
    }
  };
});

It will throw a "Database name is null or empty" exception if such URL query string wasn't built when the user clicks the Language button.

Probably this issue is unstable and other users might not experience this issue, so I see two solutions here:

1. Fix manually
2. Reach out to Sitecore Support
