FYI preview deploys were stuck today:

As of #3717 that should be resolved, and we'll correctly be serving latest main again. However, at a glance I expect the problem to persist, because the intervening PRs don't seem to touch the logic in question. Will test after latest deploy finishes and confirm.

Indeed, still a problem:

❯ cargo run --release --bin pcli -- --home ~/.local/share/pcli-preview view sync
    Finished release [optimized] target(s) in 0.26s
     Running `target/release/pcli --home /home/conor/.local/share/pcli-preview view sync`
Error: status: Internal, message: "protocol error: received message with invalid compression flag: 52 (valid flags are 0 and 1) while receiving response with status: 404 Not Found", details: [], metadata: MetadataMap { headers: {"content-type": "text/plain; charset=utf-8", "x-content-type-options": "nosniff", "content-length": "19", "date": "Thu, 01 Feb 2024 00:14:20 GMT"} }

We can rule out these PRs as the cause of the problem:

• proto: move box_grpc_svc to proto crate #3711
• pd: 🔐 extract auto-https into a standalone crate #3714
• chore: 🧹 remove dangling references to penumbra-chain #3715
• penumbra: remove chain component and move epoch management to SCT #3703

because they hadn't been deployed at the time this issue was reported.

it seems to be working for me, now.

status: 404 Not Found - I think your window manager setup made you so fast you frontran the deployment

For me too:

❯ cargo run --release --bin pcli -- --home ~/.local/share/pcli-preview view balance
    Finished release [optimized] target(s) in 0.27s
     Running `target/release/pcli --home /home/conor/.local/share/pcli-preview view balance`

I think I hadn't waited long enough for the public endpoints to update. I'll think more about how we can catch this more proactively: we should have pcli view sync pass post-deploy at the least.
