@Tbelleng can i take this?

[Tbelleng]

Yes, just check with @tdelabro before !

[aniketpr01]

@Tbelleng
Checked with @tdelabro and he approved.
Just to understand context, need to implement this RPC call which returns execution traces of all transactions included in the given block, why we may encounter the error mentioned above?

[Tbelleng]

Nice ! @aniketpr01
If the given block doesn't exist (like the value is false, or the given block hash is false) its should return the following error :
BLOCK_NOT_FOUND

[tdelabro]

The main concern is that I have no idea how you will get the execution traces.
I think you will have to re-execute the whole block in some way, while recording the trace somewhere.
What is your plan @aniketpr01 ?

[aniketpr01]

@tdelabro
As discussed on TG, I can utilize runtime_api() to simulate and re-execute tx's in an environment of block preceding the one of interest (block n-1).
This can enable me to trace and collect execution details of a block and implement this RPC call.

[aniketpr01]

yes @tdelabro, I will be working on it!

[Tbelleng]

yes @tdelabro, I will be working on it!

how its going ? @aniketpr01

[aniketpr01]

@Tbelleng
I am still debugging simulating the transactions and requesting some more time on this!
Also could you please share your Telegram id or if you can DM me? TG: aniketpr01
