I'm using the Create Site Collection task to provision site collections based on a custom developed web template (not site definition) deployed via a Farm solution. When creating a new site collection I get this error message:
<nativehr>0x81070211</nativehr><nativestack></nativestack>Cannot open file "_catalogs/solutions/[name of the web template].wsp".
This worked fine with Nintex 2.2.2.0 and does not work in 2.3.5.0. Also site collections can be created without any problems via SharePoint UI. Actually downgrading to Nintex 2.2.2.0 solves the issue (but is not really an option). So, this seems like a bug that was introduced after version 2.2.2.0.
Please help :-)!
