I am still generating this error for an expo start command and to view a page with a leaflet map - -works fine on IoS and my colleagues.

The error is also in console log as follows:

Encountered an error loading page, Object {
  "canGoBack": false,
  "canGoForward": false,
  "code": -1,
  "description": "net::ERR_FILE_NOT_FOUND",
  "loading": false,
  "target": 19,
  "title": "",
  "url": "file:///android_asset/leaflet.html",
}

I have added the following potential correction:

but, for some reason my expo start keeps failing. I am using a Red Hat distro and thought it might be my system -- so ran in root and still have errors.

Any suggestions deeply appreciated, thanks Karen
