EngineError when requesting block at slot 43200 on Zhejiang testnet

[peterbitfly]

Description

When requesting the block body at slot 80646 via the beacon api curl -v http://localhost:4000/eth/v1/beacon/blocks/43200 we get the following error:

{"code":500,"message":"UNHANDLED_ERROR: ExecutionLayerErrorPayloadReconstruction(0x1c5f2c9cbaa2e7c7abdb6fa73e7562beea21ce6af8a0e52a5634f6283db07418, EngineError(Api { error: Json(Error(\"missing field `withdrawals`\", line: 0, column: 0)) }))","stacktraces":[]}

This is also the case for all successive blocks up to block 91765 after which the api returns again valid results.

We are using lh version v3.5.0 together with erigon (latest devel)

Version

v3.5.0

Present Behaviour

Beacon API returns an error when requesting a certain range of block bodies from the Zhejiang testnet (43200 to 91765)

Expected Behaviour

API should return a block body for all requested blocks

Steps to resolve

See description

That's an Erigon issue. It will be resolved by #4028 assuming Erigon implements the PayloadBodies methods (I think they will, or may already).

You could also work around this by running Lighthouse with --prune-payloads false (and syncing from genesis).

Thanks for your quick response, will open an issue with erigon then.
