L1 Beacon API fails "cannot unmarshal hex number with leading zero digits into Go struct field"

[ErrorEater]

Here is the error output of base-node trying to connect to L1 Beacon node:
json: cannot unmarshal hex number with leading zero digits into Go struct field StorageProofEntry.storageProof.value of type *hexutil.Big

How to solve?

I'm experiencing this too, I'm dead in the water please help.

@SaulMoonves are you also using Prysm for your L1 beacon node? I wonder if there's an incompatibility that was recently introduced.

[SaulMoonves]

I am using Nethermind for my L1 execution and Nimbus for my beacon.

[roberto-bayardo]

Oh hmm, I think the key error may be this one which doesn't seem beacon node related since L1 contract data should be getting fetched from the execution client not the beacon node. This is the same error you get @SaulMoonves ?

I do believe I saw that error.

I switched to a different docker-compose provided to me by a coworker and got up and syncing (it might be out of date though), so I don't have this configuration anymore but here is a snippet of what I am using now that works:

geth:
    image: ghcr.io/base-org/node-geth:v0.10.2

node:
    image: ghcr.io/base-org/node-geth:v0.10.2
    depends_on:
      - geth

If this is dangerously out of date or something I can snapshot the data dir and try switching again to test things out if it's helpful.
