balances.LiquidityRestrictions on addProxy

[ioannist]

Hey team, stakebaby here..

I recently tried to addProxy (authormapping) on my collator and got this error: balances.LiquidityRestrictions
https://moonbeam.subscan.io/extrinsic/10202196-4

I then tried doing it via the precompile and it also reverted:

this smells like a bug that affects collators only, or accounts with a self-bond

Sik reminded me that it's a bug where you need a larger than the self-bond balance. Not a big deal for me cause I have a small self-bond, but more of an issue for collators with larger bonds.

Thanks for the report 👍 . We will have a look at it and report back once we have identifier the problem.

Hi @ioannist,

To give an update. We opened a PR upstream, if this is confirmed to be unexpected behaviour as we believe, a fix will be included in the next runtime release (runtime 3700).

Another related issue, this is part of the migration from Currency to Fungible trait (which has not been done for pallet proxy): paritytech/polkadot-sdk#226
