Just to make sure it was not a UE4 issue i went and compiled a old project of mine and it still packaged fine, i have read that the error might be blueprints. But im not that familiar with these errors so if anyone has any ideas that be a really big help!

So i figured it out, for future people referencing this error, it was indeed a blueprint issue. I would recommend going though each one located in the project and finding the culprit. It will typical be one that will not compile properly

I also think that it is a blueprint error… so i need to check every blueprint of all packs? and how do i see if there is a problem? Is there a warning symbol?

Dreamcastgamer · March 26, 2019, 12:33am

What i had to do is set the filter to blueprint, and manually open up each blueprint and click “compile”. If it compiles no problem then that blueprint is good, if it fails to compile then you found your culprit.

Hope this helps

[Solution]

All my blueprints compiled fine but I still got this error, for those in the same case: my problem was due to a corrupted variable, so I renamed all the variables to find the one that was causing the problem.

Have fun

I know you are trying to help here, but this solution is not viable in big projects and it could takes days to do that. I told this because you used “[Solution]” tag. for me the workaround for this error was to download and install a free plugin called “RefreshAllNodes” and using that plugin i have refreshed all of my BP’s and removed Intermediate, Binaries,Saved files and making a build again. It should fix the error here. Also i suspected it’s caused by a corrupted variable in a level BP. So double check all level BP’s as well
