I've already made a post but this one got closed. I also found this post which is pretty much the same error I got.

Now I got the same error for another reason and still can't find any answers on the net. I'm using the realtime database and I have a node in the database that looks like this:

private: {
  $user_uid: {
    formula: {
      formula_quota:30,
      quota_used:0
    }
  }
}

I use a button to publish some data and run a transaction to get the quota object and update it when publish is done.

I won't post the code that is not used or commented out but the quota transaction is like that:

quotaTransaction ( userUID:string, projectUID:string, state:EditorState, asObject:boolean, asProject:boolean ) {

    const quotaPath = `/private/${ userUID }/formula`;

    const quotaDoc = ref( this.db, quotaPath );
 
    runTransaction( quotaDoc, quota => {

      let nbPublish = 0;

      if ( asObject ) nbPublish++;
      if ( asProject ) nbPublish++;

      let quotaUsed = quota.quota_used;
      let formulaQuota = quota.formula_quota;

      if ( nbPublish + quotaUsed > formulaQuota ) return ( undefined );

      return ( { quota_used: quotaUsed + nbPublish, formula_quota:formulaQuota } );

    } ).catch( console.log );

}

the first time I run the quotaTransaction I get this error

RangeError: Maximum call stack size exceeded at ChildrenNode.isLeafNode (vendor.js:52413:13) at ChildrenNode.equals (vendor.js:20990:22) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31) at ChildrenNode.equals (vendor.js:20995:31)

second time I run it I get:

Any clue, maybe the firebase team can help me?
