A did_web_unresolved error should be better explained in the UI

[jchartrand]

When a did:web can't be resolved, verifier-core returns a result like the following:

{
"credential": {
"type": [
"VerifiableCredential",
"OpenBadgeCredential"
],
"name": "Teamwork Badge",

}
},
"errors": [
{
"name": "did_web_unresolved",
"message": "The signature could not be checked because the public signing key could not be retrieved from https://digitalcredentials.github.io/dcc-did-web-bad/did.json"
}
]
}

but in the UI we just show:

We should better explain what the error was.

AC1:
In grey box, under "There was an error...", put the "message" underneath to explain what the error was, for example, "The signature could not be checked because the public signing key could not be retrieved from https://digitalcredentials.github.io/dcc-did-web-bad/did.json"

Hi @jchartrand , Could you please verify the credential shared in this task description once ?

I tried to verify it in my local and production too. I see errors. The issue is with this particular credential, i tested few apart from this and they all work fine.

I could be wrong but it looks like you are pasting (into the JSON box of V+) the result from verifier-core, which isn't a VC?

You might have overlooked the bit at the very top of this issue where it says "When a did:web can't be resolved, verifier-core returns a result like the following:"

In other words, that example json is not a VC, but rather the result that comes back from verifier-core.

If, however, you take just the value of the 'credential' property on that result (which is the VC that caused the error) and paste that into VerifierPlus then it works fine.
