Query to retrieve studyID from variants not working

Hello,
I want to use the following query in order to retrieve the stidyID associated with a variant ID.

query Variant {
  indexVariantsAndStudiesForTagVariant(variantId: "1_17500056_C_T"){
	associations {
    study {
      studyId
      pmid
    }
    indexVariant {
      id
      rsId
      refAllele
      altAllele
      nearestGeneDistance
    }
    pval
      
  }
  
}
	  }

After doing this i want to use the studyID and the variantID for the studyLocus2GeneTable. Unfortunately only the sample exaple of indexVariantsAndStudiesForTagVariant is working in the API but when i am trying different variantId i always get :

{
  "data": {
    "indexVariantsAndStudiesForTagVariant": {
      "associations": []
    }
  }
}

Why this is not working ?
My plan is to try this query from R for multiple IDs. Is it possible to make it work?
If not could you please provide me with an alternative for retrieving study IDs from variantId ?

Hi Dimitris,

Hopefully the discussion linked here was helpful for your question.
