Received this error: TypeError: Cannot read property ‘name’ of undefined Rancher v0.38.1 Cattle v0.94.0 User Interface v0.50.0 Rancher Compose beta/latest ---

Yep, this is a known issue that will be fixed in the next release. Already verified. 🙂 [https://github.com/rancher/rancher/issues/2104](https://github.com/rancher/rancher/issues/2104) ---

Sorry, I thought I checked the forums before posting… Thanks for the quick response. ---

v0.39.0 was tagged as latest this morning, so you can upgrade to get this fixed. 🙂 ---

Thanks for the quick turnaround. Unfortunately the ‘latest’ did not solve my problem. I stopped all running containers and deleted the images. Just in case. I have verified that I am running: > Rancher v0.39.0 > Cattle v0.95.0 > User Interface v0.50.0 > Rancher Compose beta/latest Also, the [upgrade instructions](http://docs.rancher.com/rancher/upgrading/) did not work particularly well, so I had to jump though a few hoops to re-authorize with GitHub and generate new API keys for **rancher-compose**. It is certainly possible I am doing something wrong, but the error is the same. ---

Can you provide me some more info? What rancher versions did you upgrade from and to? Particularly what one was before v0.38.0? I want to see what happened on the authentication side because it sounds like your authentication (access control) changed a bit between releases, so I would like to test. On a fresh install, I know adding ec2 was tested but will need to check if it was verified with an upgrade. I want to try it after upgrading and uaing the same versions you did. ---

I upgraded > **FROM** v0.38.1 > **TO** v0.39.0 If I need to do a ‘fresh’ install I will gladly do that. ---

Could you try refreshing the UI? That might be required to get it working. 😄 If not, I’ll probably have some time in the next day or two to try and reproduce and give a better workaround. ---

I was unable to reproduce the error after a fresh upgrade. If you’re still hitting it, I’d recommend a fresh install unless you want me to investigate further with you. But since I’m unable to reproduce, it’s hard for me to debug. 😉 ---

Verified the EC2 functionality is working for me now. Thank you. ---
