Hi All,
I am trying to create a hosted service that runs periodically.
What it does is:
- Open a media item
- Based on the file, change some properties on a content node
- Move the media item to a another folder.
I followed this article very closely:
https://docs.umbraco.com/umbraco-cms/10.latest/reference/scheduling
So I dont think I have any obvious mistakes
When I try to call SaveAndPublish() on the contentService, to save changes to the content node I get:
System.AggregateException: 'One or more errors occurred. (Wasn't able to get an UmbracoContext)'
I thought it might have been because I wasnt creating a “scope”, so I used the scopeProvider as specified in the link above. But instead of getthing this error when i call SaveAndPublish, I get it when the scope is disposed… which makes sense.
So what is happening here, are we not able to use the content service in hosted services?
From the inner stack trace, it looks like its something to do with notification handlers:
