Warning: Arrow type "32" unknown - ignoring with rankAdjustments

[hududed]

I made the following as test.json:

{
  "tables":{
      "label":{
        "*id":"1",
        "aid": "bla"
      },
      "order":{
        "*id": "12sd312asd34",
        "+b_aid": "bla",
        "+q_aid": "bla2"
      },
      "hole":{
        "*id": "sd9f8sd9fusdfuds98u8d8fu9ds8",
        "+first_aid": "bla",
        "+second_aid": "bla"
      },

      "pos":{
        "*id": "lplppasd1213124",
        "+b_aid": "bla3",
        "+q_aid": "bla2",
        "+p_id": "06991591-ef4a-48dc-8703-89c7cd43a8fb"
      },
      "on_1_event":{
        "*id": "asd2as4d1213124",
        "state": "OPEN",
        "+o_id": "12sd312asd34"
      },
      "on_2_event":{
        "*id": "asd2as4d1213124",
        "state": "OPEN",
        "+l_id": "lplppasd1213124"
      },
      "sub_1_event":{
        "*id": "1125dfa1",
        "+key20": "123ascas123as1d..",
        "event": "PENDING",
        "+o_id": "12sd312asd34"
      },
      "sub_2_event":{
        "*id": "1125dfa1",
        "+key20": "123ascas123as1d..",
        "event": "PENDING",
        "+l_id": "lplppasd1213124"
      }
      

  },
  "relations":[
      "hole:first_aid *--1 label:id",
      "hole:second_aid *--1 label:id",
      "pos:b_aid *--1 label:id",
      "pos:q_aid *--1 label:aid",
      "label:id 1--* hole:first_aid",
      "label:id 1--* hole:second_aid",
      "pos:p_id *--1 hole:id",
      "label:id 1--* order:b_aid",
      "label:id 1--* order:q_aid",
      "order:id 1--* on_1_event:o_id",
      "order:id 1--* sub_1_event:o_id",
      "pos:id 1--* on_2_event:l_id",
      "pos:id 1--* sub_2_event:l_id"
  ],
  "rankAdjustments":"{rank=min on_2_event pos sub_2_event}{rank=same label hole}{rank=max on_1_event order sub_1_event}",
  "label":""
}

and I got multiple errors Warning: Arrow type "32" unknown when running dot test.dot -Tpng -o test.png - then some outputs are missing the correct cardinalities. Please advise

hi, it seems to not produce any warnings for me. my only guess is that it's something to do with the specific layout you're trying to force. The arrows always go from left to right, so trying to lay tables on top of each other messes that up. Which is probably why the cardinalities get confused. Removing rank adjustments fixes this.
