$searchMeta stage : Query should contain either operator or collector

I am using mongoDB Atlas searchMeta stage to query the facets data. Below is my query

{
index: “default”,
facet: {
operator: {
text: {
query: “BL65FJ3”,
path: “householdId”,
},
},
facets: {
categoryCounts: {
type: “string”,
path: “category”,
numBuckets: 100,
},
},
},
}

I am getting below error
mongot returned an error :: caused by :: Query should contain either operator or collector

Hi there, can you share the full query with $searchMeta and provide your JSON index definition?
