It sounds like the same as https://github.com/realm/realm-js/issues/6129 and we released a fix for it in v12.2.0.
Has this potentially regressed since as I'm using v12.6.0? Will downgrade to v12.2.0 to see if it makes a difference and get back to you
downgrade to v12.2.0 to see if it makes a difference
Thanks!
Same error:
Original update function:
Error: Attempting to create an object of type 'User' with an existing primary key value '341'
Adapted update function:
Error: Attempting to create an object of type 'Organisation' with an existing primary key value '454'.
So the first error is expected:
realm.write(() => {
session.user = updatedUser;
});
where updatedUser
is an unmanaged object will attempt to first add it to realm and then set session.user
to it. In the case where the user already exists, you're supposed to get an error.
The second code snippet points to a legitimate bug though, however I've been unable to reproduce it. I've attached my attempt to repro this - if you can modify it in a way that triggers the duplicate PK error, let us know and we'll continue investigating.
Thank you for getting back to me, I will have a look ASAP.
Given the above situation, what would be the correct way to update this nested object? I would assume that because it comes down with the same primary key as the object currently stored in the DB, it would successfully match these up and update it, I don't quite understand why it would cause an error?
Also as this worked fine in v11, is there something specific that has caused this breaking change? If I downgrade again, everything works as intended.
Did
update(() => {
session.user = updatedUser;
});
work with v11? If it did, it's definitely unintended and likely a bug with v11. The other code snippet - i.e.:
realm.write(() => {
realm.create(
'session',
merge({}, original, changes),
Realm.UpdateMode.Modified,
);
});
Should work in both v11 and v12 and is the right way to do it. If it doesn't work with v12, then we should definitely fix it, but I can't repro it so far.
Yep, both worked fine with v11, will try and reproduce with a test when I have a moment and get back to you

Any chance you have a moment to create a reproduction case for us?

Description
Similar issues: https://github.com/realm/realm-js/issues/6322 https://github.com/realm/realm-js/issues/6239
We have been using Realm v11.10.1 without issues, since upgrading to v12.6.0, we are encountering errors updating nested objects.
We receive an updated version of an object from our server in JSON format. We want to update the Realm object in the devices local database so that the changes are reflected.
The object we have looks like this, with each name being its own Realm table:
We update the object in Realm like so:
and call this function as such:
We receive this error:
Attempting to create an object of type 'User' with an existing primary key value '341'
In an attempt to fix this, we have adapted the update function to be the following, this also works on v11.10.1 without issue:
Which is then called as such:
This also fails, however giving an error a layer deeper:
Error: Attempting to create an object of type 'Organisation' with an existing primary key value '454'
Stacktrace & log output
