Onboarding!

Getting this in the error log that I have not seen before:

Sep 04 07:10:00 ip-172-31-41-212 start-assethub-node0.sh[10278]: 2023-09-04 07:10:00 [Parachain] Could not decode the head data. error=Error { cause: Some(Error { cause: Some(Error { cause: None, desc: "out of range decoding Compact<u32>" }), desc: "Could not decode `Digest::logs`" }), desc: "Could not decode `Header::digest`" }

It looks like there were an error parsing the files. Can you confirm the files are ok? And I will try to re-onboarding it

[alistair-singh]

Which file fails to parse? I have double-checked the files, which look to be created and uploaded correctly. I think maybe our chainspec is wrong, as we had to use asset-hub-kusama-local as a base chainspec, which is kusama-like. We might need to customise the chainspec to make it rococo-like.

I get an AccessDenied message when trying to access the new files

I have assigned permissions. Please try again.

[AlexD10S]

I have reset the code and the state, I think this will be enough. But if still not working I will try to offboard and onboard the parachain again

Blocks are being produced! Thanks!

Perfect, closing the issue then
