unable to decode some storage items

[insipx]

While running tests for sidecar with polkadot-js versions v6.0.5 came across a few types that failed to decode properly (sidecar PR)

thought this was related to metadata v14 update, looks like an issue with AccountId's maybe?

At which block/chain for the events? (Checked Polkadot, Kusama, Westend for the block in the PR and they all decode without issues on the apps UI which is on 6.0.5)

For v13 chains, ensure it is on 6.0.5, earlier has issues in a variety of ways. (The PR is still on 6.0.2 which is known problematic)

There are quite probably still some dragons lurking, but before 6.0.5 they are now known dragons. Happy to look at specific chains/block/hashes where there are any issues, on the latest API, aka also failing in e.g. the apps UI.

Sorry for jumping in this late, currently OOO. But that being said, @jacogr 6.0.2 as you said is where the issues lie in our PR but a bump to 6.0.5 fixes our decoding issue. Thanks again.

I think this issue is solved, thanks for the help @jaco, I'll close this
