Hi, Just for the record: with our without cache server the error is the same. I just didn't know where to post this as it's clearly related to the new Asset Pipeline V2 and there are no clear sub-forum for that. Context: I have a big project, all migrated to 2019.3.3, I needed to install Entities and weirdly enough at the end of that installation I got a message in console stating that I needed the Asset Pipeline V2 to use it. Fair enough, let's go for actually 6 hours of upgrade to this pipeline V2. Once it's finished, my project seem to work fine overall. But... I have this error absolutely all the time. It's really annoying as there are no log trace, no explanation on what this is and of course if I google the error I find all the "Assertion failed on expression" error possible except that one: Code (CSharp): Assertion failed on expression: 'gOnDemandAssets->empty() || GetOnDemandModeV2() != AssetDatabase::OnDemandMode::Off' Clearly this is related to the new pipeline but I have no idea how to fix this. It pops: -When saving the scene -When entering play mode -When exiting play mode -When compiling a script -When creating a folder in the project view I didn't try but I think if I sneeze that will also pop the error. While it seems harmless, it makes readability of the console horrible and as anyone here, I just don't want errors that I can't do anything about if I don't have a proper log behind. Can anyone help me please? And I have no idea on how to reproduce it seriously.. I can't pack my project as it's way too big. It just happened after migrating from pipeline v1 to v2... that's all I know Thank you by advance.
