Using a freshly created create-near-app I am trying to dev-deploy and getting this error:

Starting deployment. Account id: dev-1635099366550-3101206, node: https://rpc.testnet.near.org, helper: https://helper.testnet.near.org, file: out/main.wasm
An error occured
Error: Can not sign transactions for account dev-1635099366550-3101206 on network testnet, no matching key pair found in InMemorySigner(MergeKeyStore(UnencryptedFileSystemKeyStore(/Users/<username>/.near-credentials), UnencryptedFileSystemKeyStore(/Users/<username>/Documents/Projects/new_test_app/neardev))).

I'm unsure what's causing it or what needs to be done to resolve it. I've checked the /Users/<username>/.near-credentials credentials directory and there is a .json file containing credentials. I tried near clean & rebuilding, ensured I had done near login even tried with sudo thinking it might be a permissions error.

I don't have a reason for the "why" behind this happening, but eventually I tried deleting the dev-1635099366550-3101206.json file in /Users/<username>/.near-credentials (the first dev account it created) and then re-ran near dev-deploy.

This created a new dev account and seemed to work fine. Re-running near dev-deploy after that also seemed to work fine, redeploying the contract to the same account.

I got the same problem and I tried to open the web on another web browser, the problem disappeared.

[UPDATE] I clean the browser local storage and import the wallet again, everything works fine. Local storage value

Use NEAR connected account interface instead. You can read more at here : https://near.github.io/near-api-js/classes/walletaccount.connectedwalletaccount.html
