Extension not installed on grain

[stephenlautier]

I'm not entirely sure if something has changed or why is this happening. However, we recently are getting the following. Any ideas?

Extension not installed on grain SignalR.Orleans.Groups.GroupGrain attempting to invoke type Orleans.Streams.OrleansCodeGenStreamConsumerExtensionMethodInvoker from invokable Orleans.Runtime.ActivationData

THat is weird... Can you come down to gitter? would like to debug it...

It seems i've got the same issue. Did you ever find a solution to this? Exception seems to be the same as above, or very similar at least.

[stephenlautier]

@emilekberg Recently it seems ok.. few weeks ago we were still having it tho.

Last thing we've changed is, we updated to latest of this lib, but we are still on 2.3.5 orleans

[stephenlautier]

@emilekberg actually it seems it still happens, much less in frequency but it does happen

Did you find a solution for this? I see the same exceptions unfortunately.

Edit: Anyone who is having this issue: Try using this fork mentioned in this issue. This seems to have fixed it for me. Thanks @stephenlautier

@digisimon im glad that worked for you! We do have several fixes/improvements in our fork; we will need to contribute back to this at some point
