Basemaps not showing with Beta 3

[mpboyle]

I created and downloaded my first app using Beta 3 and none of our basemaps show in the basemap widget.  They all appear when I configure the basemap widget, but if I click on the basemap widget within the app builder or after downloaded, nothing shows.

Has anyone else experienced this?...or have any suggestions what the issue is?

Matthew,

   In Beta 3 the ability to specify baseamps and operational layers in the main config.json has been partially removed and broken. I don't know if there are any concrete plans to fix this or not in the final release.

[mpboyle]

Is there a way to get our basemaps to show in the basemap widget...?

[RobertScheitlin__GISP]

Matthew,

   I can get the basemap gallery widget to use the basemaps from my server as long as they have the same spatial ref as the webmap that I am using

[mpboyle]

Our basemaps are all in State Plane, as are the services overlaid on our basemaps.  Is there something in the code where the WKIDs are off...?

[RobertScheitlin__GISP]

Matthew but is your WebMap that you begin the whole Web AppBuilder application preparation (when on the map tab), does that web map use state plane? I have been completely unsucessful in using a state plane web map and then trying to use state plane basemaps in the basemap gallery widget (at least in  Beta 3).

I had the same issue. I went to the config_Basemap.json file and removed the empty tags like {}, (line 75 in your file) and it worked again.

Stan McShinsky‌ - that did it, thanks for the tip!
