Frequently asked questions

Can this error occur even if the plugin was working previously?

Yes — if the plugin package is removed, the storage container access policy changes, or the plugin version is deprecated, previously working pipelines can begin failing with this error.

Does this error affect built-in connectors or only custom ones?

Error 27002 specifically relates to custom plugins; built-in Fabric connectors do not rely on the same plugin download mechanism and would not trigger this code.
