Unable to delete project

Hi All,

I’ve recently taken to trying to clean up some obsolete projects within Octopus. This project has been cloned several times and can now be deleted as it’s been superseded. However when I go to click the “Delete Project” button on the confirmation screen I get the below error and subsequent stack trace.

Error resolving type specified in JSON ‘Octopus.Core.Resources.Forms.Paragraph, Octopus.Client’. Path ‘Form.Elements[0].Control.$type’, line 1, position 290.

Hi,

Thanks for getting in touch! It looks like an old reference in the data. If you could run the following query on your database (backup first), it should resolve your issue.

UPDATE dbo.Interruption SET Json = Replace(json, ', Octopus.Client', ', Octopus.Core')

This is a change we made in 3.4.3, and so that I can track down the cause, did you upgrade from an earlier version recently? Or was the project imported from an a previous version?

Hope that helps!

Hi Robert,

Thanks for getting back to me so quickly. The query you provided seems to have done the job perfectly.

We do update about once a fortnight (if a new release is available) and the project has existed since version 3.1. It wasn’t imported from any previous version.

Let me know if you require any more information.

Kind Regards,
Ben

Hi Ben,

Awesome, thanks for letting me know. I’ve reviewed the code and figured out how it occured, it was a problem that only occured in 3.4.2 that I fixed incorrectly.

Regards,
