I see that there is an SPID in the config: src/tests/web3_tests/principal_test_config.json. Could it be related to this?

[elichai]

Nope, It's something to do with your report/quote.
You can try printing it before the panic, add a print of the report string here /root/src/enigma-tools-u/src/attestation_service/service.rs:143

[Isan-Rivkin]

@fredfortier could you cd into enigma-tools-u and run cargo test see if attestation_service passes?

[fredfortier]

Yes, these passed fine.

The error suggest that it's missing the field platformInfoBlob. This makes sense because it's not in my report but it is in the ASResult struct. Somehow my SGX driver behaves differently. I'm not sure if this an attribute that's always supposed to be in the report or only for some platforms. Now that I understand the root cause, I can work around it.

[fredfortier]

I modified src/attestation_service/service.rs:21 to:

#[derive(Serialize, Deserialize, Debug)]
pub struct ASReport {
    pub id: String,
    pub timestamp: String,
    pub isvEnclaveQuoteStatus: String,
    pub platformInfoBlob: Option<String>, // Made optional
    pub isvEnclaveQuoteBody: String,
}

I'll let you guys decide if this is an appropriate resolution, but it fixes my issue for now. The principal node is now behaving as advertised.

[Isan-Rivkin]

Good idea, apparently platformInfoBlob is optional in Intel's API
