Object reference not set to an instance of an object

Dear Support,

We are using SQLBackupAndFTP version 12.2.9 installed on Windows 2019 server, to backup databases from PostgreSQL 11 server installed on Ubuntu 18. The job is sometimes ending in error:
10.07.2019 10:34:22 [Info] Starting job "SQL02 " - “Full”. Computer “BACKUP01”. App v.“12.2.9”
10.07.2019 10:34:23 [Info] Connecting to PostgreSQL Server: PostgreSQL 10.9 (Ubuntu 10.9-1.pgdg18.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0, 64-bit.

10.07.2019 10:34:27 [Error] Job execution error: Object reference not set to an instance of an object. Computer name: “BACKUP01”
10.07.2019 10:34:27 [Error] Job "SQL02 " finished with “1” errors

When I try to run job immediately again (2nd time), it runs correctly.
What is the cause of this behaviour? Is there anything to prevent this error?

Thanks in advance
