When configuring load balance adaptive we are seeing the following error on cli:

ae1 {

    apply-groups NNI;

    description 32001.GE10L.ORLHFLPR0QW.ORLDFLIE2AW:AGG:ORLDFLIE2AW:AE1:10.72.91.37;

    aggregated-ether-options {

      load-balance {

        ##

        ##

        adaptive;

      }

      minimum-links 1;

      lacp {

        periodic fast;

Load balance adaptive is only supported on MX/PTX/QFX10002/QFX10008. You can confirm the same on the following link: https://apps.juniper.net/feature-explorer/feature-info.html?fKey=5891&fn=Adaptive+Load+Balancing+%28ALB%29
