I know I saw this in here before but

I know I saw this in here before but cant seem to find any resolution to it... I'm currently getting errors saying my cursor is invalid and not sure how to fix 🤔 My code looks like so:

let cursor: string | undefined, complete = false

do {
    const { keys, list_complete, cursor: cur } = await env.Tracking.list<R2LatencyMetadata>({ cursor, prefix: 'TimeSeries/R2' })

    complete = list_complete, cursor = cur

    // Do some things with keys
} while (!complete && cursor)

let cursor: string | undefined, complete = false

do {
    const { keys, list_complete, cursor: cur } = await env.Tracking.list<R2LatencyMetadata>({ cursor, prefix: 'TimeSeries/R2' })

    complete = list_complete, cursor = cur

    // Do some things with keys
} while (!complete && cursor)

Seems like I am still getting errors sometimes but a lot less than when I originally posted the above. Just had a request fail saying to following cursor is invalid if it helps (kv 7a23d30e52584ab3bb7e435dc46425b7):

@walshydev sorry for the ping but I assume I am doing nothing wrong and I still get these errors saying my cursor is invalid with the above code. Curious if you would be able to ping the right people for this 🙂 Its like ~5-10% of requests that fail currently

I'd probably ping @kian for this tbh LuL

If it helps also anytime it fails its always the second page the (the first one that actually has a cursor) at least that I have seen

kian•3y ago

i'd assume cursors are just an opaque string - but if anyone had the tools to see what the error was it's you not me :^)

however it appears that I can't test much anyways since KV throws a 429 at me for a namespace with like 5 keys

UnsmartOP•3y ago

Yeah I get 429s every once in a while in waves also dont really track that though. Easier to see the cursor failing since I run it on a cron and it throws an error I can see on my worker summary 🤷 even my list operations are getting 429s now actually normally its only the writes interesting

oh i thought this was R2 not KV I got confused by the type LuL
