Symbolic pulse raise `TypeError`

[miamico]

Environment

• Qiskit Terra version: 0.21.1
• Python version: 3.9.12
• Operating system: macOS Monterey 12.4

What is happening?

When trying to instantiate a SymbolicPulse as follows:

GaussianSquare(
        duration=280,
        amp=0.1,
        sigma=12,
        width=100)

I get the following error:

TypeError: lambdify() got an unexpected keyword argument 'real'

How can we reproduce the issue?

GaussianSquare(
        duration=280,
        amp=0.1,
        sigma=12,
        width=100)

What should happen?

A GaussianSquare pulse object should be instantiated

Any suggestions?
