I’m trying to bring some design components from Figma into Android Studio using the Relay plugin. I pasted my Figma file URL and kept the default theme setting as androidx.compose.material3.MaterialTheme.
The import process fails with a transformation error. Here’s the main error message I’m getting:
com.google.relay.androidstudio.plugin.importer.FigmaServiceException: Command:

#5 new InstanceNode.fromJson (package:figma_to_adin/src/figmarest.dart:567)
The error continues through many more lines but it seems like there’s an issue with parsing vector nodes from the Figma file.
I’m pretty new to using Relay and not sure what might be causing this parsing problem. Has anyone seen this before or know what I should check in my Figma file?
Any help would be great!
check your figma file for vector shapes with empty or missing properties. i hit this same error - turned out i had imported svg icons without proper fill data. relay cant handle null values in vector nodes. try duplicating your file and delete half the elements to test the import. keep narrowing it down until you find the problematic element.
This VectorNode parsing error usually happens when your Figma vectors are malformed. I ran into the same thing with a design that had vectors from boolean operations or external imports. The vectors look fine in Figma but have broken internal data that Relay can’t handle. Select all your vectors and right-click ‘Flatten’ to simplify them. Also check for masked vectors or clipping paths - they often have null properties that break imports. If it’s still failing, duplicate your file, remove all vectors temporarily to test the import, then add them back one by one to find the problem element.
This parsing error happens when the Relay plugin hits unexpected null values in your Figma file’s vector properties. Usually, it’s from layers that got messed up during design work. I’ve seen this with vector layers missing fill or stroke data, or components that weren’t duplicated properly. Before importing, flatten any complex vector groups in Figma and make sure all shapes have fill colors. Another culprit is hidden layers with broken references - clean out any unused or invisible elements. If it’s still acting up, try exporting individual components instead of the whole file. That’ll help you figure out which element is breaking the transformation.
Had the same problem last month with a complex design file. That null type casting error usually means there’s corrupted or broken vector data in your Figma file. For me, it was vector elements that weren’t built right - missing stroke properties or incomplete paths. Try making a simple test file with just basic shapes and text to see if it imports. If that works, add your original stuff back piece by piece. I found certain custom icons or complex vectors were breaking the parser. Also check for detached instances or broken components - they can mess up the transformation process too.
This happens when Relay hits inconsistent vector data in your Figma file. I’ve seen this a bunch - it’s usually mixed vector formats where some were made in Figma and others came from Illustrator or Sketch. The plugin expects everything to match but finds null values instead of proper data. I fix this by opening the file and redoing any vectors that came from external tools using Figma’s native vector tools. Look especially at anything you copy-pasted from other design files or imported assets. You can also check your version history and try importing from an earlier version to figure out when things broke.
