sqlitebrowser debian packages are unable to verify signature during dput

I was trying to manually upload stable package to ppa for Ubuntu 20.04 and received SignatureVerifyError

$ dput ppa:linuxgndu/sqlitebrowser ../sqlitebrowser_3.11.2~focal_source.changes
Checking signature on .changes
gpg: ../sqlitebrowser_3.11.2~focal_source.changes: Error checking signature from 832FD7AA62EBC033: SignatureVerifyError: 0
Checking signature on .dsc
gpg: ../sqlitebrowser_3.11.2~focal.dsc: Error checking signature from 832FD7AA62EBC033: SignatureVerifyError: 0
Uploading to ppa (via ftp to ppa.launchpad.net):

  Uploading sqlitebrowser_3.11.2~focal_source.buildinfo: done.
  Uploading sqlitebrowser_3.11.2~focal_source.changes: done.
Successfully uploaded packages.

It says packages has been uploaded but i don't see builds in ppa. Is this issue with my key or something else ?
