Open Cloud: Get Instance always returns code 422 on children inside StarterPlayerScripts or ServerScriptService

Bug Reports Cloud Services Bugs

#1

Using the Get Instance method (Instance | Documentation - Roblox Creator Hub) on an instance inside either ServerScriptService or StarterPlayer.StarterPlayerScripts always returns code’: 422, ‘message’: ‘Response payload too large to return’.

I have tested this on the instance types: “Script”, “LocalScript”, and “ModuleScript”.

To Replicate:

  1. Create a new script inside ServerScriptService
  2. Using the Cloud API, use the Get Instance method on the newly created script.
  3. It will return error code 422

Note: If you move the exact same script into ReplicatedStorage and then get the instance with Open Cloud, it works as intended.

We’ve determined that it’s the ListInstanceChildren operation (Instance | Documentation - Roblox Creator Hub) that is returning the 422 error rather than GetInstance.

ListInstanceChildren returns the script contents of any Script instances as well as metadata. That means if there are many scripts under the same parent (or a few large ones), the total size of the result can be large enough to exceed the maximum response size, resulting in the 422 error. This is intended behavior.
