Edge debug_traceTransaction warnings while Blockscout fails to fetch internal transactions

Description

Running Blockscout to explore a Polygon Edge network, logs show Blockscout errors and potentially related Edge warnings.

Blockscout error:

Your environment

• ubuntu Kubernetes nodes on AWS
• blockscout deployed with official helm chart (blockscout v5.2.3-beta, chart 1.1.5)
• edge v1.1.0

Can you send us how the rpc call looks like to that debug_traceTransaction that BlockScout is sending to Edge? Basically, how the request looks like (which parameters are set, etc).

[RonTuretzky]

I think you should upgrade to edge 1.3, solved most of my problems with blockscout

[sebastiendan]

@RonTuretzky I just tried with edge v1.3.0 and still face the issue if I re-enable the internal tx fetcher

I'm not sure how to get that from blockscout's logs. Would have any advice?

From what I understand polygon edge doesn't support internal tx fetching , is that true @goran-ethernal ?

[goran-ethernal]

@RonTuretzky No, Edge does not support that unfortunately.
