feature Id Alphanumeric

Question

I have feature Ids that are alphanumeric and other numeric. The numeric Ids are kept as is but the alphanumeric ids are set undefined. Is it a way to set the addSource method to accept Alphanumeric values in feature.id?

I try promoted by it is return always undefined for all features.

Note: this happens in mousemove events and querySourceFeatures

Currently there's no way to support this because the Vector Tile specification only allows integers as feature id — you would have to store alphanumeric id as a feature property for it to work with promoteId. Closing as a duplicate of #2716.
