Tracer is required

On rpc.linea.build, the default tracer is not supported. You must specify a tracer in the options object. Supported tracers are callTracer and prestateTracer. flatCallTracer is not supported.

Parameters

• blockHash: [required] 32-byte block hash.
• options: [required] Object specifying the tracer:
  • tracer: [required] "callTracer" or "prestateTracer".

Returns

Array of trace results with the same shape as debug_traceBlockByNumber.
