Thanks for getting in touch! Can you please go to https://your_octopus_server/app#/configuration/features, click Sync button and wait for the task to complete successfully? Then can you go and try again the same action that originally triggered the problem? If you still see the problem please let me know the name of the community templates that causes it.
After runnign sync manually I didn’t get any errors s will wait and see if we will get any of them tommorow and not sure what si triggering this sync.

I’m tryign to figure out why we have those warnning
Thank you for providing logs. From what I can see it looks like the logos of those two templates are missing but Octopus expects them to be available. Do you have an idea why they might not be there? Has the instance been migrated recently? Has the location of Artifacts folder changed?
The data is in inconsistent state so to solve your problem we need to provide those 2 missing logos. The following steps are the same for both templates and the only difference is the template name and the logo file.
Execute Select Id from dbo.CommunityActionTemplate Where [Name] = 'AWS - Create Cloud Formation Stack' and remember the result, this is the name of the missing logo. It should look like this: ComunityStepTemplates-NUMBER
Go to Artifacts folder and confirm there is no file with the name you found in the previous step. There should be plenty of other files that start with ComunityStepTemplates.
Download AWS category logo from and save it with the name you found in step #1 in Artifacts folder. Note, the file should have no extension. Please use SQL category logo for the SSRS template
Now the sync process should not produce any warnings.
but the sync task (attached) still have a lot of warnnings it seems that warnning affect many templates.
We;e also migrated the octopus to the new server and had to also repoint the folders in database:
UPDATE [dbo].[Configuration]
SET JSON = ‘{“ArtifactsDirectory”:“D:\Octopus\Artifacts”}’
WHERE Id = ‘artifactstorage-single’
I’ve alo synced the Artifcatcs folder content so which has just few files (Capture.png)
Thank you for the logs. I spent a bit more time on this issue and it turned out that our migration process doesn’t export the logos of community step templates. I fixed that problem and made the community step templates sync a bit less strict so it can deal with missing logos. You can track the progress of this work here. It should be released within a week or so.
Please let me know if this doesn’t solve your problem.
