Emu_batch.source.show() problem

[balewski]

Describe the bug
I’m resurrecting my old Bloquade code which uses parametric waveform and now I see crash in emu_batch.source.show()
ValueError: Variable sweep_time not assigned

Despite I do it after all variables have been assigned and
emu_batch = batch.braket.local_emulator().run(shots=30)
completed emulation.

Minimal broken example
