I'm stuck with querying Firestore REST API. I can figure out how to filter by a regular key but I can't figure out how to query by nested object key.
Basically, in the browser client, I can do
firestore.collection("channels")
.where("members.[memberID]", "==", true)
.get()
However, when I try to do the same in the REST API, it said Invalid Argument. I was trying to do
{
"structuredQuery": {
"where": {
"fieldFilter": {
"field": {
"fieldPath": "members.[memberID]"
},
"op": "EQUAL",
"value": {
booleanValue: "true"
}
}
},
"from": [
{
"collectionId": "channels"
}
]
}
}
but it gives me "Invalid Argument" error on fieldPath
. Does anybody know how to query Firestore REST API based on nested object?
Thank you!

I asked for Firebase support and they said special characters in fieldPath
such as "-" in my case can be escaped using back tick or back slash. It is mentioned in the documentation. In my case, I'll need to do
members.`[memberID]`
I hope this is helpful for you guys.
