Hi, I encounter the same error

Update: upgrade to version 4.0.2 didn't resolve the problem

[emostov]

I cannot reproduce this issue.

I tried v4.0.0, v4.0.1, and v4.0.2 - they all worked for me against blocks/4355787 on the polkadot network.

• How are you installing api and running api-sidecar?
• Can you double check your api-sidecar version?
• Can you check the exact version of the @polkadot scoped deps it is using (i.e. @polkadot/api, @polkadot/types etc). For the polkadot-js deps you should be able to find them in the node_modules folder where api-sidecar is installed; check there packages package.json files to see there version directly. Should be 4.2.1 for the latest sidecar.

Does the issue resolve if you upgrade the node to the latest client release?

[anhcao142]

I can't reach my server right now. I'll update as soon as possible

Thanks, it resolved when I upgrade to v4.0.2. (My old sidecar version is v3.0.4)

@emostov Upgrade Polkadot to 0.8.29 and Substrate to 4.0.2 solve the problem for me. My previous version was 0.8.26-rc2. Kind of weird since the release note doesn't force you to upgrade

@anhcao142 what version of Sidecar where you on before? Just trying to figure out if it was upgrading Sidecar that fixed it or upgrading the node

[anhcao142]

It's 3.0.4. Hope that help

I have the same problem at block 4355787. My sidecar version was v3.0.4 and the problem was solved by upgrading it to v4.0.4.
