Eravelo, AWS made some changes to api call validation so we need to do some updates to the racks.
We have a test release ready with a fix. If you have a dev environment you would like to test it on let me know.

Thank you @Brian-G
Deploying this release seem to have fixed the issue.
Is this release ready for production?

@eravelo We have some customers using it in production now and I just updated our production rack also.

We still get the error sporadically, I can do `convox ps` and it sometimes works, sometimes fails. Odd…

Hi,
If it can help, I notice that with the new version 20211012210133 `convox ps` works well except during the build of the image.

Updated our dev env to 20211109164223 now and 'convox ps" works but ‘convox rack ps’ still returns error: InvalidParameterException: Invalid identifier

We also get the same issues with `convox ps` during builds:
```auto
$ convox ps --rack /qwe
