I ran into a similar issue recently while trying to upgrade my stack. It seems like FusionAuth is generally pretty stable on the LTS versions, but things can get a bit 'interesting' if you're jumping to the absolute latest bleeding-edge Node release before they've officially validated it.
I've found that sticking to the even-numbered LTS releases usually saves a lot of headache with the client libraries. Are you seeing specific crash logs, or is it just a dependency resolution error during the build?
