Problems using outdated AP30 with virtual XG ([Unknown] unknown AP model encounterd: AP30, dropping)

Question

Hi! I just bought an used UTM 220 and some AP30 and AP50 for my home lab. The Wireless features on the UTM are locked because of no license. So I just installed an XG virtual machine. 
 The AP is getting an IP address but I always get "[Unknown] unknown AP model encounterd: AP30, dropping.". 
 Does anyone of you know what I could try next? My currently installed version is SW-17.5.12_MR-12-664. I also tried 18.0.4 and 19.0.1 before. The 19.x does not support AP30 anymore and the 18.0.4 also could not find them. 
 Thank you very much!
