Figma Relay Import Error Transformation Error

Question

I attempted to import some themes that were on figma into my android studio using Relay. When importing, I put in my link and left the theme as: androidx.compose.material3.MaterialTheme

I got an error with this stacktrace:

com.google.relay.androidstudio.plugin.importer.FigmaServiceException: Command:
C:\Users\{username}\AppData\Roaming\Google\AndroidStudio2022.3\plugins\relay_android_studio\bin\win64\figma_to_adin

Stack Trace:
Severe: Failed to transform https://www.figma.com/file/{redacted}/{redacted}?type=design&node-id=7-400&mode=design&t={redacted}:
