Bloqade101 tutorial aquila run_async submission validation exception

[ryanhill1]

Describe the bug

Following Bloqade101 tutorial. Configured AWS credentials and copied code in exactly, but got exception trying to submit program to Aquila.

Minimal broken example

from bloqade import start

program = (
    start.add_position((0, 0))
    .rydberg.detuning.uniform.constant(10, 1.1)
    .amplitude.uniform.piecewise_linear([0.05, 1.0, 0.05], [0, 15, 15, 0])
)

result = program.braket.aquila().run_async(100)

Expected behavior

If tutorial program code is correct, should submit without error.

If tutorial program code is incorrect, should be updated.

Update: It turns out it was just a problem with the given example program. PR linked above giving fix.

However, it would be nice if we could make the error message a bit more descriptive, particularly in the line:

For the amplitude field, rate of change of values (between the 0-th and the 1-th times) is 3.000000E+14, more than 250000000000000.0

it would be great to add units or ballpark of how much the rabi amplitude would need to be lowered by.

This example should work as is without having to change the parameters. We have run this in the past so there is probably something else going on here.

Oh wait nvm, yeah the ramp up and down time should be 0.06 to make this work.
