Figma Weave Generating Wrong Code? Try This Fix

When Figma Weave outputs incorrect code, broken layouts, or invalid design tokens, it is usually due to a breakdown in context translation. Because Figma Weave uses the visual layout engine alongside Large Language Models (LLMs) to generate frontend code, small structural issues in your design canvas can cause massive hallucinations in the generated React, HTML, or CSS code.

If your code exports are mismatched, contain outdated properties, or completely ignore your component structure, use this step-by-step troubleshooting guide to restore generation accuracy.

Why Figma Weave Generates Incorrect Code

Unlike standard text generators, Weave relies on the layout properties, naming conventions, and constraints defined in your Figma layers. If Weave cannot parse your layer semantics, it falls back on predictive modeling, which leads to generated code that does not match your canvas. Common symptoms include: * Hardcoded absolute positions instead of responsive Flexbox/Grid CSS. * Raw hex colors instead of your declared design tokens. * Hallucinated Tailwind classes or invalid React component imports.

Follow these structured steps to fix the underlying issues and align Weave's output with your design intent.

1. Enforce Figma Auto Layout

If Weave is generating messy CSS containing top, left, and absolute positioning values, your Figma canvas lacks proper constraints.

1. Select the frame or component group you want to generate code for.
2. Look at the right-side properties panel. If Auto layout is not enabled, click the + icon or press Shift + A.
3. Ensure your containers are set to either Fill container or Hug contents rather than fixed pixel dimensions.
4. Re-run Weave on the auto-layout frame. The model will now translate your design into responsive Flexbox properties (e.g., display: flex, justify-content, align-items) instead of guessing relative pixel offsets.

2. Standardize Layer and Component Names

Weave uses layer names to determine class names, variables, and semantic HTML elements. If your layers are named 'Frame 4892' or 'Vector 12', the generator has to guess their structural purpose.

1. Open your layers panel (Sidebar).
2. Rename parent frames using lowercase, hyphen-separated structural names (e.g., card-header, profile-avatar, submit-button).
3. Mark structural semantic frames with standard web naming conventions. For instance, naming a frame nav or footer tells Weave to generate semantic <nav> and <footer> tags rather than generic <div> wrappers.
4. Hide or delete empty vector layers and unused text boxes, as Weave attempts to write rendering logic for invisible canvas elements.

3. Specify Your Framework in the Prompts

When Weave lacks specific framework constraints, it may mix syntaxes (e.g., using React's className alongside standard HTML attributes or mixing up Tailwind with inline styles). Inform the model of your specific codebase requirements.

1. Open the Weave prompt input field.
2. Add a system-level constraint at the start of your instructions.
3. Do use: 'Generate functional React components using Tailwind CSS utility classes only. Do not output inline styles or external CSS stylesheets.'
4. Do not use: 'Make this look like my design.'
5. If your codebase uses a specific CSS-in-JS library, explicitly state the import path: 'Use styled-components for layout styling. Import from "styled-components" at the top of the file.'

4. Clear Figma's Local App Cache

Sometimes, Weave utilizes an older, cached version of your design file metadata. If you have updated your auto-layout properties or variable bindings but the generated code still reflects the old design, clear Figma's cache.

For macOS: 1. Quit Figma. 2. Open Terminal and run the following command: rm -rf ~/Library/Application\ Support/Figma 3. Restart Figma, open your project, and re-run Weave.

For Windows: 1. Close Figma. 2. Open the Start menu, search for %APPDATA%, and press Enter. 3. Locate the Figma folder and delete it. 4. Relaunch Figma and test the generation again.

5. Map Design Tokens Manually

If Weave is failing to translate your local styles into variables, you must explicitly feed the variable definitions to the model.

1. Highlight the component and copy your variables to your clipboard as JSON (if using Figma Variables).
2. Paste your token definitions directly into the Weave generation interface.
3. Instruct the model: 'Map all canvas-level hex values to these local tokens: [Paste JSON]. Do not write hardcoded color values.'

When to escalate

If Figma Weave consistently generates syntax errors, invalid JSON, or refuses to follow explicit system instructions across multiple files, the underlying LLM partition may be experiencing an API degradation. Check the official Figma Status page (status.figma.com) to verify if the Figma design systems or AI services are currently operational. If services are normal, submit a bug report via the Figma Help Center, detailing the target design framework and providing a copy of the malformed output.
