Topic: Bitcoin RPC loadwallet Error - Wallet file verification failed (Read 198 times)

Last time I checked, the wallet file needs to have a very specific name (wallet.dat), it's the folder name that indicates the name of your wallet, and as such, only the folder name should be included in a loadwallet call, without any path.

Have you copied it to the correct directory that I've pointed-out in my reply?
Namely: .bitcoin/wallets ; either paste 'backup.dat' inside or create a 'backup' folder there, paste 'backup.dat' file inside it and rename it into 'wallet.dat'.

Because if you did, there shouldn't be any error when you used the said commands.

loadwallet takes the name of a wallet, which is the name of the directory within the wallets/ directory that contains the wallet.dat file.

You can use the restorewallet RPC to restore a wallet from a backup. This takes the name to give the restored wallet, and the path to the backup of a wallet.dat file. It will create the necessary directory structure, copy the backup to the correct location, and name everything correctly. The restored wallet will already be loaded, and can be loaded or unloaded in the future using the name that you gave it when doing the restore.

Note that this RPC is currently only available in version 23.0.

(I'm assuming testwallet is the first wallet you used and one that works with the rpc command, is it or does that still not work)?


Why are these different, is there a reason for that?

Can you sudo chmod 711 them (according to a search engine that should be RWX--X--X you might want to confirm before doing it?

See if there's a difference between the subfiles of both of those directories too.

Of course I'm sending right away

Can you check the permissions on the wallet file and post the here (ls -l in the parent directory where the wallet file is and then show us the first 10 characters that should look something like -rwxrw----) just in case it's that, you could also try doing that with the parent folder if you made it yourself to check bitcoin core has the rights to see files inside the folder.

Sorry, same error.

I try with all kinds of link structures / I get an error whether I put it or not. I tried all link structures.

The parameter has to be either a folder, either a filename (not a file path!). You've still put a path there, of course it's not working.
Maybe nc50lc's answer makes it clearer?

I get file validation error when directory name and folder path are correct

If I mistype the directory name I get another error because, Wallet file verification failed.

Response body: Wallet file verification failed. Failed to load database path '/lastwallet/hey.dat'. Path does not exist.

Either put 'backup.dat' inside .bitcoin/wallets dir or
Create a 'backup' folder inside .bitcoin/wallets dir, paste your 'backup.dat' file there and rename it into 'wallet.dat'.

Then load it using loadwallet backup.dat for the former or loadwallet backup for the latter.

I didn't use this, but according to the error message you may have to have either


or



but certainly not the full path.
Of course, this may mean some adaptations in filenames or paths.


All the examples on the net seem to be loading wallet.dat without a path. Is it a problem for you to put into the datadir the wallet(s) you're planning to load?

Hi!

I am using my own bitcoin node server. I get the following error while making load wallet with RPC.


Request body:

{"jsonrpc": "1.0", "id": "curltest", "method": "loadwallet", "params": ["/home/bitcoin/.bitcoin//backup.dat"]}


Response body:

{
    "result": null,
    "error": {
        "code": -4,
        "message": "Wallet file verification failed. Invalid -wallet path '/home/bitcoin/.bitcoin//backup.dat'. -wallet path should point to a directory where wallet.dat and database/log.? files can be stored, a location where such a directory could be created, or (for backwards compatibility) the name of an existing data file in -walletdir (\"/home/bitcoin/.bitcoin\")"
    },
    "id": "curltest"
}

how can i bypass this error
