What is the expected behavior?

A parametric Qiskit circuit should be converted to a Braket parametric circuit.
Currently, trying to convert a Qiskit parametric circuit to a Braket circuit like so:

from qiskit_braket_provider.providers.adapter import convert_qiskit_to_braket_circuit
from qiskit.circuit import Parameter

theta = Parameter('θ')
qc = QuantumCircuit(1, 1)
qc.rz(theta, 0)

yields the following error:

TypeError: ParameterExpression with unbound parameters ({Parameter(θ)}) cannot be cast to a float.

Expected outcome: This should return a Braket circuit with Rz gate and FreeParameter θ

I'm also interested in working on this issue as part of the Unitary Hack. Can I be assigned to this challenge?
Thank you!

@natestemen Just updated. Could you update the UnitaryHack website to reflect @king-p3nguin as the bounty closer? https://unitaryhack.dev/projects/qiskit-braket-provider/
