[BUG] Data transformation errors with new update. There is a parallel version of the node inside the same scenario. Also it doesn't work properly when getting _id from MongoDB. For same node it gives error half the time

All data transformation nodes started doble quoting the _id from MongoDB for some reason.

It solved using Object as type of data instead string

Then, I had another bug, that all data transformation nodes without icons didn’t work neither with string or object.

See that there isn’t any icon on the data type of this transformation node. I don’t know why it is is buggy, but after creating new ones the initial bug still persists.

Now when I use Object type, sometimes it states that _id is not a object and sometimes it works properly with object type. It is very strange that for same node it simply works half the time.

Also when I use the string type with _id it double quotes always. So it is giving error on all scenarios when trying to update the DB.

@jan is there any fast workaround around this bug?

Having the same issue. I’ve been using atlas so my work around has been to use objectid with an http request node to the rest API.
