rekor-cli: get fails for some entries

[SantiagoTorres]

It appears that even with the latest build, download fails on some entries:

santiago at ~/.../sigstore/rekor ✔ ./rekor-cli get --log-index 1063252
&{0 } (*models.Error) is not supported by the TextConsumer, can be resolved by supporting TextUnmarshaler interface

It happens with particular entries, and reproducibly, so I think it's an issue with the unmarshaller for the cli for a particular type. Now, it's hard to know which type it is, because get is not working...

[SantiagoTorres]

Huh, it works now, I wonder why. The entry type was minisign fwiw...

[SantiagoTorres]

there are others that still fail, e.g., (1051951), but I have my reason to believe this is not reproducibly failing

[SantiagoTorres]

Indeed, a couple of runs and it starts working for this entry again.

We (Agent Integrations for Datadog) saw the same error a few days ago, too. If you look at previous issues for the same kind of error message, it looks like it's a generic error message that can be misleading.

Since we haven't seen this for 2 months, closing. Feel free to reopen if needed.

At Datadog, we worked around it by separating calling the rekor-cli into its own, small CI/CD job, so we can easily retry on any transient failure w/o affecting anything else
