[alex-semenyuk]

Interesting, the same error...

[EnriqueL8]

@SupernaviX could you take a look at this one?

[EnriqueL8]

Is this hostname added to /etc/hosts?

The error from docker logs is

firefly-cardanosigner-1   | 2025-07-07T11:01:17.411655Z ERROR init_state: firefly_cardanosigner: error=EOF while parsing a value at line 2 column 0 config=FireflySignerConfig { api: ApiConfig { address: "0.0.0.0", port: 8555, info: Info { title: "FireFly Cardano Signer", summary: None, description: None, terms_of_service: None, contact: None, license: None, version: "", extensions: {} } }, file_wallet: Some(FileWalletConfig { path: "/wallet" }), log: LogConfig { level: "info" } }
firefly-cardanosigner-1   | Error: EOF while parsing a value at line 2 column 0

it looks like the configuration for the signer is either unavailable or malformed.

@Quantumplation @EnriqueL8 the wallet to use for this test is provided as a secret named DEMO_WALLET. When tests are run from a fork, they don't have access to that secret.

I'm not sure what the appropriate fix is. That secret is the signing key for a preview wallet; it's not extremely sensitive, but it probably shouldn't be committed in plaintext.

[EnriqueL8]

Oh I see... so the way we normally do this is by approving runs on the PR from forks

[EnriqueL8]

uhm that might not work we already have this
