Help with error reload class

[gitingua]

Hello colleagues
When running the command (/opt/splunk/bin/splunk reload deploy-server -class Class_Name -debug)

There was no such error before. Literally today got out with what it can be connected?

Will setenv SPLUNK_CLI_DEBUG to "v".
In check_and_set_splunk_os_user(): In env found *no* SPLUNK_OS_USER var.
