Hi Brett, thanks for reporting this.
In 0.4.0, the Filters and Tag classes were deprecated, replaced by the ListSecrets class (with a list of Filter instances). The Tag class hadn't been modified for a while before that, so indeed this is probably caused by the latest release.
I have one idea of what might have caused this, which I only noticed this morning... could you confirm what kind of setup you've got?
- Are you specifying config through the Web UI, or are you using Jenkins CasC?
- Have you upgraded the plugin on an existing Jenkins, or did you install the plugin afresh on a new Jenkins?
