Check if field exists in any map value

Question

I have the following structure:

   "my-map": {
      "my-key1": {
         "field-to-find": {}
      },
      "my-key2": {
         "field-to-find": {}
      },
      "my-key3": {}
   }

I want to check if field-to-find exists in any of the values of my-map. Is this possible?

Things I tried:

1. Using my-map.exists(i, has(i.field-to-find)) -> doesn't work because i returns just the key, not the value of the map
2. Using my-map.exists(i, has(my-map.i.field-to-find)) -> doesn't work because i is treated as a string, is there a way to reference it as a variable?

Answer 1

I figured out mymap.exists(v, has(mymap[v].fieldtofind)) works.
