Cannot share 'Esri default basemaps' to custom basemaps group

[JackSilburn]

Our organisation has aerial photography, which we want to include into our 'basemaps' selection. We also still require the Esri default basemaps to be selectable.

I am following this article here:

Create a custom basemap gallery for your organization 

In the final steps, you can chose to share the Esri defaults with the custom basemaps group. The button is called 'Share vector basemaps':

However, this button functionally does nothing when pressed. Inspecting my Chrome browser actually shows an error, upon button press:

dojo.js:516 Uncaught Error: dijit._TemplatedMixin template:!text
at Object.<anonymous> (dojo.js:516)
at dojo.js:46
at dojo.js:521
at String.replace (<anonymous>)
at Object.g.substitute (dojo.js:520)
at Object._stringRepl (dojo.js:516)
at Object.buildRendering (dojo.js:517)
at Object.create (dojo.js:301)
at Object.postscript (dojo.js:300)
at new <anonymous> (dojo.js:150)

I don't know if this is the cause or related? I can't find any articles whereby people are experiencing the same issue.

Any help is appreciated,

Thank you

Did you find a solution to this issue? I am having the exact same problem. When I click the "Share vector basemaps" button I get the same error in my Chrome browser:

Uncaught Error: dijit._TemplatedMixin template:!text

Looks like the issue is with the settings when you create the Group. I think it has to do with the "What items in the group can it's members update?" When it was set to "All items (group membership is limited to the organization)" I got the error.

I recreated the group with "Only their own items" selected instead and was able to share the ESRI basemaps.

My group settings are in the attachment.

Cheers
