Missing `balance_exemptions` in `/network/options` -> `allow`

[fboucquez]

Hi team,

According to https://github.com/coinbase/rosetta-specifications/blob/master/models/Allow.yaml#L28,

The balance_exemptions is required in the Options's Allow entity. The field is missing in the following service implementation:

https://github.com/coinbase/rosetta-ethereum/blob/master/services/network_service.go#L65

Note that BalanceExemption could be an empty object!

There is a bit of inconsistency. 2 possible fixes:

• Fix the service by adding balance_exemptions. That field could even be an empty object.
• Remove balance_exemptions from required in the openapi spec.

I know that in general, this is not a big issue, a client app can just ignore the missing balance_exemptions. In my case, I'm using generated typescript clients using openapi generator. The parser breaks the whole call because it expects the field to be present.

Thanks! Fernando

Thanks for raising this. We will take a look to see what's the best way so that parser doesn't break for you.
