Every form has a retention policy, for it to clean up form submissions based on the values set a scheduled job is ran, the default settings for this job is to be ran a midnight every day. The Job is called Form Submissions Cleanup.
You could try manually running this job to see if the same errors occur.
It might be worth raising a support ticket with Optimziely to see whats inside this Job and if it sets and property values during its run on the Form Contaner, it could be trying to see a value for a property which is not CultureSpecific on a non master langauge. (Or DotnetPeek)
Good morning everyone,
around midnight i have many log warnings from episerver. It seems to be related to the Epi-Forms. What is causing this?
Servername 2022-11-18 00:00:24,819  WARN EPiServer.DataAccess.Internal.ContentSaveDB: Cannot save common property PartialSubmissionRetentionPeriod on non-master language de on content with id 5604_107217
Servername 2022-11-18 00:00:24,840  WARN EPiServer.DataAccess.Internal.ContentSaveDB: Cannot save common property FinalizedSubmissionRetentionPeriod on non-master language de on content with id 5604_107217
..... (many Content-Ids)
Edit: It's not new, always in the night, is there a job running which is causing this? We have thousands of these entries.
Thanks in advance,
