Unsolved Flexbody Error on mesh ....VX node not found

Im having an annoying problem with snorkel doesnt show up because of the error said at the title.
I dont know what's that error anyways.

Code:

{
"midsize_snorkel": {
    "information":{
        "authors":"BeamNG",
        "name":"Snorkel",
        "value":200,
    },
    "slotType" : "midsize_snorkel",
    "flexbodies": [
         ["mesh", "[group]:", "nonFlexMaterials"],
         ["midsize_snorkel", ["hopper_snorkel","midsize_fenders_L"]],
         ["midsize_snorkel_pipe", ["midsize_fenders_L"]],
    ],
    "nodes": [
         ["id", "posX", "posY", "posZ"],
         {"group":"hopper_snorkel"},
         {"collision":true},
         {"selfCollision":true},
         {"nodeMaterial":"|NM_PLASTIC"},
         {"frictionCoef":0.7},
         {"nodeWeight":2.5},
         {"engineGroup":"engine_intake"},
         ["snork", 0.68103, -0.22417, 1.46138],
         {"group":""},
         {"engineGroup":""},
    ],
    "beams": [
          ["id1:", "id2:"],
          {"beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
          {"beamSpring":501000,"beamDamp":500},
          {"beamDeform":5000,"beamStrength":"FLT_MAX"},
          {"deformLimitExpansion":1.2},
          ["snork","fe7l"],
          {"deformLimitExpansion":""},
          {"beamSpring":51000,"beamDamp":250},
          ["snork","fe8l"],
          ["snork","fe3l"],
          ["snork","fe9l"],
          ["snork","fe4l"],
          ["snork","fe13l"],
          ["snork","fe11l"],
          ["snork","b14l", {"breakGroup":"fenders_L"}],
          {"beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
    ],
    "triangles": [
          ["id1:","id2:","id3:"],
          {"group":"hopper_snorkel"},
          {"triangleType":"NONCOLLIDABLE"},
          ["snork","fe8l","fe3l"],
          {"triangleType":"NORMALTYPE"},
    ],
},
}

 

I think in the flexbodies the group "midsize_fenders_L" should be "midsize_fender_L"

 

Somehow only the snorkelpipe appears but the snorkle doesnt

--- Post updated ---
it works now!
I removed "hopper_snorkel" group from flexbody section
