Jobs List page crushed: AttemptErrors not present in response

[spatecon]

Trying open http://localhost:8080/jobs?state=completed on non-empty environment after the merge of #344 resulted in JS error and page crush if job list not empty:

react-dom_client.js?v=200b8c56:6264 TypeError: Cannot read properties of undefined (reading 'map')
    at apiAttemptErrorsToAttemptErrors (jobs.ts:113:17)
    at apiJobToJob (jobs.ts:96:11)
    at Array.map (<anonymous>)
    at jobs.ts:231:33

The above error occurred in the <MatchInnerImpl> component.

Seems like errors field is null (omited) in the /jobs api response and leads to error in apiAttemptErrorsToAttemptErrors.

GET http://localhost:8080/api/jobs?limit=20&state=completed

}

Because the struct RiverJobMinimal inhandler_api_endpoint.go:1115 doesn't contain errors and metadata anymore.
