trace_* or erigon_* namespaces. Migrate the trace_* methods to their debug_* equivalents:
Pass
flatCallTracer ({"tracer":"flatCallTracer"}): it returns traces in the same Parity flat format as the old trace_* methods, so it is the closest drop-in replacement. The erigon_* convenience methods have no Bor equivalent — use the standard eth_* methods instead.
On Bor, eth_getProof returns state proofs only for roughly the latest 128 blocks; historical proof queries are not available.
