KV giving null while doing get even though the key exists

There is no error from KV and also there is no response with correct value.

You'll probably need to give us more context on the problem. Do you have a code sample or something? Are you testing locally or are you working in production?

Production @JustinNoel The code snippet is as follows:

let res = await env.KV_NAME.get(kv_id)
.then((r) => {
    console.log("Successful response from KV => ", r);
    return r;
})
.catch((e) => {
    console.warn(" error in getting the from kv ", e);
    return null;
});

let res = await env.KV_NAME.get(kv_id)
.then((r) => {
    console.log("Successful response from KV => ", r);
    return r;
})
.catch((e) => {
    console.warn(" error in getting the from kv ", e);
    return null;
});

Here is the sample code... Sometimes, I'm getting null in the then part of the response, not the catch part. So the request is successful while the return response from kv is null even though there is value for the said key

Errors are only thrown when something goes wrong internally. Since a get of an empty key isn't wrong, then no error is thrown. Also, you seem to be combining await and then

The key itself is present and has value in kv store Mistake on my part Production

Hello, I’m Allie!•8mo ago

No, I just meant that, if a key wasn't present, that wouldn't be an error, so it wouldn't hit the catch handler. How long has it been since it was inserted/updated? Updates can take 60 seconds or more to show up, depending on how recently you tried to access the key, and what cacheTtl you set, if any.

Right About 1 week

Try just doing this:

let res = await env.KV_NAME.get(kv_id);
console.log(`res = ${res}`)

let res = await env.KV_NAME.get(kv_id);
console.log(`res = ${res}`)

If you to catch errors, I would suggest using a try catch instead of then and catch.

I'm not getting error. The kv is just returning null even though value for the key exists

Michał @ yournextstore.com•8mo ago

How do you know it exists?

VMSS•8mo ago

By directly checking in the KV store, by searching with the key

JustinNoel•8mo ago

Is KV_NAME bound to the correct KV namespace?

ASK•8mo ago

Yes

Tin Cap•8mo ago

Can you sanity check that by adding something in the KV web view and then trying to retrieve it in your code? I very much suspect there is an issue on your side somewhere.

I did do that too... No dice
