The bonder sync is producing numerous, non-blocking errors with a "403 Forbidden"

See original GitHub issue

All instances of the bonder (live and local) are producing unexpected errors. This does not appear to be negatively affecting anything and it appears to not block anything, however, this should be well understood and fixed.

To reproduce, run the bonder locally and observe errors. Alternatively, look at existing, recent bonder logs.

Some data points:

They all appear to give the same error: 403 Forbidden
They all appear on the Hop mainnet RPC endpoint

Some examples of errors from running locally:
