Mixed route together with linetee throws error no attribute coords

[SimonQuantumhw]

Information

• Qiskit Metal version: newest
• Python version: idk
• Operating system: win11

What is the current behavior?

ERROR [rebuild]: ERROR in building component name=line, error='NoneType' object has no attribute 'coords'

Steps to reproduce the problem

Create mixedroute with anchors and between anchors and connect it to lineetee second_end

LineTee1 = LineTee(
design,
name='Lt1',
options={'pos_x': '500.0um'},component_template={'falseparam1': {'falseparam2': 'false-param', 'falseparam3': 'false-param'}},
)LineTee1 = LineTee(
design,
name='Lt2',
options={'pos_x': '-500.0um',},component_template={'falseparam1': {'falseparam2': 'false-param', 'falseparam3': 'false-param'}},
)LineTee1 = LineTee(
design,
name='Lt3',
options={'orientation': '90.0',
'pos_x': '-2500.0um'},component_template={'falseparam1': {'falseparam2': 'false-param', 'falseparam3': 'false-param'}},
)LineTee1 = LineTee(
design,
name='Lt4',
options={'orientation': '270.0',
'pos_x': '2500.0um'},component_template={'falseparam1': {'falseparam2': 'false-param', 'falseparam3': 'false-param'}},

What is the expected behavior?

It should create route
