My Pipeline has 2 solids: [image 1] print_user_information -> solid_sleep My goal is to be able to run launch-execute only "solid_sleep" on GKE. Where am I doing wrong? print_user_information: • Input: Optional<string> • Output: Int solid_sleep: • Input: Int In the dagit playground, when I do "Launch Execution" with this config, it works ( creates new tab showing the GKE Job launch ) [Image 2]

solids:
  print_user_information:
    inputs:
      cmd: 
        value: "echo hello world"

But when I updated the solidSubset to run only "solid_sleep", and do "Launch Execution", it fails [Image 3 + 4] Config:

solids:
  solid_sleep:
    inputs:
      sleep_time: 2

However If I do "Start Execution" Instead, it works [Image 5] I opened the dev console and found some stack trace. posted in the comment section. [Note 6] ( adding images and notes .... done.)

Image 1:

Image 2 : successful launch for full pipeline

Image 3 + 4: Config error :

Image 5: Start-execution subset only solid 2 successful

Note 6: Stack trace:

we'll be releasing 0.8.0 on thursday so if you'd prefer to wait for a release, this should be resolved by that release
