Got error "Value '17056882' is not valid System.Double type" when download image file with GPS value

Boopathi

I am attempting to download an image file using the Dropbox API, but I am encountering an InvalidCaseException. Could you please suggest a solution? I have included the sample code and the stack trace below.

code :

fileResponse = await dbx.AsAdmin(userId).WithPathRoot(new PathRoot.NamespaceId(user.Id))
.Files.DownloadAsync(x.PathLower);

Stack trace :
