I have began to do some experiments with immudb. I am inserting some data and it is inserting fine there. However, if I try to get a value like this :

const getRes = await cl.get(getReq);

I get an error "Key not Found". How can I know if a certain key is available before I do the Get query?

There is no "exists" operation exposed by immudb but it shouldn't be an issue to receive "key not found" error.

Depending on your use case, sometimes you can use a scan operation. It will give you a list of keys matching given prefix. That could be useful if you work on set of values sharing common prefix.
