GraphQl where does not filter in Staging

Question

I have a GraphQl query that works in development but doesn't work in Staging.

query all_Products($region: Alpha2Code!) {
    variantsByregion(region: $region
      where:{isB2B:{eq:true}}
      ) {
        items {
          productCode,
          isB2B
        }
    }
}

if I run the above query in my development it will filter with isB2B but as soon as I use this query in Staging I get whole data.
