Westmint block #5482732 can not be decoded

Westmint block #5482732 can not be decoded

[Imod7]

Same Issue

I can confirm that I see the same error message when requesting

• the same block (5482732)
• and while also connected to Westend Asset Hub

either by :

• using polkadot js apps (RPC call chain > getBlock)
• or Sidecar (endpoint blocks/5482732)

Findings / Thoughts

This error message is triggered here so the call missing is in section = 5 and is the method with index 69 right ? Based on the docs, the section signifies the pallet of the extrinsic but in Westend Asset Hub I do not see any pallet with index 5 🤔. Maybe I am missing something.

Any ideas which method/call is causing the issue ?

Reproducing the error with pjs

Trying to reproduce the same error with pjs. After running this github gist code the error returned is the same as above

and the line where the code breaks is (the getBlock call for the specific blockHash) :

const signedBlock = await api.rpc.chain.getBlock(blockHash);
