How can I run conditional steps based on the exit code of a prior command?

[wheat grotto]

For instance if I run aws sts get-caller-identity it will return a non-zero exit code if the credentials have expired.

Therefore if exit code is non-zero I want to run a conditional step to refresh the token.

I've tried using this approach but it seems that as soon as the withExec command produces a non-zero exit code it crashes and doesn't proceed.

there is an optional expect argument to withExec

that does exactly what you want. then you can access exitCode

How can I see that argument from the API docs?
https://docs.dagger.io/api/types/#container

I found a more detailed one.

👍

https://docs.dagger.io/api/reference/#Container-withExec

process "aws sts get-caller-identity" did not complete successfully: exit code: 254

expect is supposed to be of type ReturnType
https://docs.dagger.io/api/reference/#definition-ReturnType

I've set it to ReturnType.ANY but it still fails

Because ReturnType.ANY only allows exit codes 0-127?
