Naming an account struct RNGEvent causes an invalid account discriminator

[asktree]

If I make an #[account] struct called RNGEvent, and then use program.account to fetch it, I get an invalid account discriminator error. If I rename the struct to Cum or RngEvent it works fine.

I am guessing this is to do with the consecutive capital letters in "RNGEvent" though I have not tested this.

This issue appears both in anchor-ts and anchor-client-gen.

I think this explains it pretty much, unless & Until I'm missing something.

Maybe the discriminator should just ignore casing entirely?

Just dealt with this issue, it was a pain to debug, from my experimenting, any struct you name with more than 2 uppercase letters will not work and will give you the error invalid account discriminator. This seems to be new, because the candy machine program itself uses an CollectionPDA struct, and it works fine (was compiled with older version of anchor, 0.21.0 i think).
