Addressables 1.2.4 NullReferenceException: AddressableAssetEntry.GatherAllAssets

Unity Engine

Unity 2019.3b7

I don’t know what happened, I started getting an error message every time I tried to open the Addressables window, and the window itself is empty. But if I run the project everything works as expected. But I can’t change addressable assets right know. Is there anything I can do, to fix this without recreating all addressables groups?

Ok I found the problem. Looks like one of the assets failed on import. I re-imported it and everything is back to normal. But I think it will be better to handle an exception in that place and print the path of the asset, that was failed.

Hey @iamarugin I do think a better log message in that scenario would be useful. Would you mind filing a bug and posting the case number here so we can get that into our backlog to look at. Thanks!

Hey, sure, Case 1194340

@iamarugin Sorry to resurret an older thread but how you do know which asset failed the import and how do you reimport ?

I opened the code of Addressables and insert Debug.Log right before the line, that was failed.
Btw, @davidla_unity QA have closed this issue, because they can’t reproduce it.

@iamarugin Hm, thanks for the heads up. I’ll see what I can find out. At the very least there’s the ticket that I threw into our Jira so it won’t get lost.

Edit: Actually, thinking about it, I need to check with one my team members. I think they literally just brought this same issue up in a different context and might be working on a fix. I’ll have to see.

Hey, this is great news, thanks!
