We're converting our chain from PoA to PoS in this PR https://github.com/DataHighway-DHX/node/pull/52/commits/7c8c96939ab6a2b77dd3a2f4bef427e831dafbda But when I run the chain with those latest changes I got error `TypeError: Cannot read property 'vesting' of undefined` when I tried to go to the "Accounts", "Transfer", or "Extrinsics" app using polkadot.js.org/apps, as explained here https://matrix.to/#/!XOxcnpiHXHhAjJfRFP:matrix.parity.io/$0oidO-aZvsjMRdskB2nig6P_Y4CjH4Gc6TMrl4V7ZB8?via=matrix.parity.io&via=matrix.org&via=matrix.dapp.org.uk After cloning https://github.com/polkadot-js/apps and debugging the error, I found that this change resolved the error and the error no longer appears when I access those apps
