| Message | Feature is not yet supported: <Feature> |
Cause
LAMA0099 is a generic error meant to signal that your code uses a feature that Metalama doesn't support yet. The <Feature> placeholder describes the unsupported feature.
The current version of Metalama defines this diagnostic but never reports it: unsupported features are reported with more specific diagnostics. Because nothing in Metalama reports it, the article has no example.
Resolution
If you see LAMA0099, you're probably using an older version of Metalama:
- Read the description of the feature in the message and avoid using this feature, or find another way to achieve the same result.
- Update the Metalama packages to the latest version. The feature may be supported, or reported with a more specific diagnostic.
