Filed names cant end with number?

[yangit]

I will sound stupid but may this be a bug?
If name of the field ends(contains?) with a number than optimistic updates will not work.
Here is the stripped down repo to reproduce:
https://github.com/yangit/relayNumberBug

There are 2 branches which are different by one field name containing one extra symbol!
Here is the link to a diff

By looking at it could you guess why such a small change could break optimistic updates?

I have no errors in console in any case
I rebuild schema
I refresh my browser using hard refresh
I replace thisIsUniqueName using global project search
I knock my head against the wall

Any ideas?

Tgat is super weird. Relay treats field names as opaque - it doesn't substring them or treat numbers in the field name specially (not on purpose, at least). Are you sure there's nothing else different, and that you've updated the schema appropriately with the right field names? Just checking to rule out obvious things.

I definitely rebuild schema. I get all sorts of errors if I forget.
I even embedded schema rebuild into npm start to avoid forgetting.

I'm not sure but I tried my best to eliminate all listed issues.
If you think I can try something else let me know.
BTW I can change name to any other unique name if it does not end with number.

Anyone mind doing npm install then npm start and looking at localhost:3000 in two different branches?
Detailed instructions are given here
I would deeply appreciate that.

Here is an example of what I see in debugger
_conversations3sn0Oo:conversations(first:1000)
That is for a field called conversations
That number 3 there is definitely added by Relay
Something to do with params?
Could that be a reason?

Relay Modern is now out so I am closing these old issues that pertain to the legacy core, because nobody is actively working on that anymore. Please file any new issues relevant to the new core separately. Thanks!
