[asiniscalchi]

it seems it's the api the problem: I run locally polkadot.js and it works with the following:

but the one published is not working with:

---

So it seems v10.12.6 working. v13.2.1 not working.

[asiniscalchi]

find out that we are missing some metadata LAOS side: 2024-09-26 11:26:37 PORTABLEREGISTRY: Unable to determine runtime Call type, cannot inspect sp_runtime::generic::unchecked_extrinsic::UncheckedExtrinsic

[asiniscalchi]

the error was exposed by this delta : https://github.com/polkadot-js/api/compare/v13.0.1...v13.1.1

It should be the usage of metadata V15.

[piggydoughnut]

Thank you for such a great debug 🙏🏽 The update to v15 is in the works. So hopefully soon all will be 🚀 😊

[asiniscalchi]

Hi @piggydoughnut is there any tool that could check if our metadata is correct ? I really scared that the problem is our side but I dunno how to verify it. ( and it's a kind of critic bug for us ... our users can't interact with the chain )

[asiniscalchi]

The line that is failing: https://github.com/polkadot-js/apps/blob/6d20dfc291a5a2be882cc01ce0eda5273551e143/packages/react-components/src/AccountName.tsx#L52

[piggydoughnut]

Hey @asiniscalchi, sorry for delay, this will solve crashing explorer - https://github.com/polkadot-js/apps/pull/10967 Should be up soon.

Investigating the format issue now.

Hi @piggydoughnut, thanks for your help on this issue! The patch solved the crash issue. In case it helps, these are the final issues still remaining:

• impossible to add an H160 address in the address-book tab (see screenshot, the save button is always disabled)
• balances not shown (see screenshots)

Let us know if there's anything we can help with. The LAOS team would definitely prioritise providing support.

Thanks! Toni

Hai @tonimateos ! Thanks a lot for providing the information about the other issues - it certainly helped :) All the fixes are pushed now, everything should work fine after the next api release which should be soonish (2 weeks max)

P.S. Here are sneak peeks of the fixes 😉
