Hi,

i currently used version 2026.3.0 and told a colleague to create a schedule to execute a job every week on Friday.

Now, we wanted to change this job to every first day of month and i pointed him to the right setting in the GUI for that.

The scheduler did not execute this job - and he told me that he cannot find this scheduler anymore.

Error message:

Error deserializing C:\ProgramData\UniversalAutomation\Repository\.universal\schedules.ps1. Parameter set cannot be resolved using the

specified named parameters. One or more parameters issued cannot be used together or an insufficient number of parameters were provided.

Resolution:

modify schedules.ps1

From: New-PSUSchedule -Script 'prod\Export Infos.ps1' -TimeZone 'Europe/Berlin' -Name 'Export Infos' -Minute 1 -Day @("FRI") -EveryMonth -DayOfMonth 1

To : New-PSUSchedule -Script 'prod\Export Infos.ps1' -TimeZone 'Europe/Berlin' -Name 'Export Infos' -Minute 1 -EveryMonth -DayOfMonth 1

Then the schedule was visibile again.

Please check/remove previous settings by saving new values.

I dont know if this error is already fixed in newer versions - i did not find any hint in release notes.

But for sure, i'll udate now.
