Answer 1

Delete

• user.id
• appUser.id

identities from your /home/pritam/fabric-samples/asset-transfer-basic/application-javascript/wallet directory.

The error that occurred is already documented in the app.js file that exists under the asset-transfer-basic directory:

// NOTE: If you see  kind an error like these:
/*
    2020-08-07T20:23:17.590Z - error: [DiscoveryService]: send[mychannel] - Channel:mychannel received discovery error:access denied
    ******** FAILED to run the application: Error: DiscoveryService: mychannel error: access denied

   OR

   Failed to register user : Error: fabric-ca request register failed with errors [[ { code: 20, message: 'Authentication failure' } ]]
   ******** FAILED to run the application: Error: Identity not found in wallet: appUser
*/
// Delete the /fabric-samples/asset-transfer-basic/application-javascript/wallet directory
// and retry this application.
//
// The certificate authority must have been restarted and the saved certificates for the
// admin and application user are not valid. Deleting the wallet store will force these to be reset
// with the new certificate authority.
