Adding a KML file through the Add Data widget returns the error "The file <name> cannot be successfully uploaded.".

Workaround

Create a custom widget by copying the folder add-data located on located on <EBDevInstallFolder>\client\dist\widgets\common and change the line bellow in the file widget.js located on <CustomWidgetFolder>\dist\runtime and deploy it on your environment.

From:

return`${null===(o=(0,e.getAppStore)().getState())||void 0===o?void 0:o.portalUrl}sharing/kml`

To:

return`${null===(o=(0,e.getAppStore)().getState())||void 0===o?void 0:o.portalUrl}/sharing/kml`
