Cannot reconstruct what the problem might be with so little information.
Does the conversation in this issue maybe help?
Hello all i also have skey and vkey file , but i cant use it with the latest cardano cli js or any where else ,i have some funds on my wallet which i am unable to use.please help on this to how i can my wallet
Have you tried with cardano-cli directly?
I tried cardanocli-js which i previously used but now it’s not working
https://github.com/shareslake/cardanocli-js is just a wrapper around cardano-cli (and hasn’t seen any development since March by the way).
In order for that to work, you have to have a cardano-node running and synchronised on the same machine and cardano-cli installed and usable by that Javascript wrapper.
I’d really try to use them with cardano-cli directly without that cardanocli-js wrapper first to reduce possible sources of problems.
