Cause: The active target was read before it was configured.
Check:
- the runner is setting the target before flow code executes
- tests and local tooling call
configureTarget(...) explicitly
expect Throws A Stub Error
Cause: The package code is running outside the runner-provided execution environment.
Check:
- the flow is running through the expected runtime
- local tooling is not calling the type-safe stub directly
Callback Is Missing page Or driver
Cause: The flow uses the no-launch path, so launched runtime objects are not injected into the callback automatically.
Check:
- whether the flow should use
{ target, launch: true }
- whether the flow should call
launch() imperatively inside the callback
