Hi All,

We are currently preparing to migrate over to lightning and are conducting some tests in one of our Dev sandboxes.  I have tried to convert about 5 custom buttons that call Javascript using the Lightning Experience Configuration Converter tool and have received the error in the attached screen shot each time I select the convert or convert and deploy options.  I clicked on the link to contact support however, Lightning is not one of the options.  MyDomain is enabled in production.

Any ideas as to who I can talk with to address this issue?  I would rather not have to recreate these buttons if i don't have to.

Thanks,

Adam
