When I use NODE-RED enviroment to send transaction using Parity, the signer doesn't ask only for the password as usual but also for the local key file, which I can't locate in my laptop (I'm looking in the directory /home/.local/share/io.parity.ethereum).
Why does this happen? Where can I find this file?
Thanks in advance,
Simone
Multiple possible reasons.
From your screenshot, the account doesn't have a name, so most probably it's not present on the accounts list. I assume that either it's from a closed vault or the request was issued via RPC, so probably you sent it manually, and the account is simply unknown to parity.
The signer thinks it's an external account. This generally means that the signer's account selector allowed you to select an account that isn't available for Parity currently. This sometimes happens by closing a vault in one tab while using a DApp in another.
If you created it this account just right now via RPC, then it may just needs a page reload. The account list in the redux state doesn't track accounts creation/deletion except when in its own tab.
But account in a vault is the most plausible explanation. Unlock your vault and let me know if you could figure it out.
Disclosure: I work for Parity.
