键必须是非空字符串，并且不能包含“.”、“#”、“$”、“/”、“[”或“]”

Question

I am trying to write with admin permission two places at once on firebase functions. Getting this strange error:

Error: Firebase.set failed: First argument contains an invalid key (/Auction/TD6MKEhS/-Kn9cMUPkk)

My code is:

var newPostRef = admin.database().ref().child("History/" + this.customeruid + '/' + this.quoteid + '/' + this.banuid).push();
var newPostKey = newPostRef.key;
var updatedBidQuote = {};
// Create the data we want to update
let postData = { creationBidDate: admin.database.ServerValue.TIMESTAMP, customeruid: this.banuid, quoteCompanyCreatoruid: this.customeruid, Amount: this.banBid };
updatedBidQuote['/Auction/' + this.customeruid + '/' + this.quoteid] = postData;
updatedBidQuote['/History/' + this.customeruid + '/' + this.quoteid + '/' + this.banuid + '/' + newPostKey] = postData;
return admin.database().ref().set(updatedBidQuote);

I check the object of postData and didnt have any (.keys or strange value)

Answer 1

您只能将完整路径传递给update ，因此最后一行应该是：

return admin.database().ref().update(updatedBidQuote)

Answer 2

For me, I had unnecessary curly brackets. I changed from

return admin.database().ref().update( {updateObj} );

to

return admin.database().ref().update(updateObj);
