According to VS Code's file icon theme specification, the fileExtensions object should map file extensions to icon IDs. However, for compound extensions like "file.camel.yaml", only the last extension part is used by VS Code (i.e., "yaml"). To match files with patterns like ".camel.yaml", you need to use the fileNames property instead, with patterns like ".camel.yaml" and "*.camel.yml". The current implementation will not correctly match these files.

Suggested change

	"fileExtensions": {
	"camel.yaml": "_camel-yaml",
	"camel.yml": "_camel-yaml"
	"fileNames": {
	"*.camel.yaml": "_camel-yaml",
	"*.camel.yml": "_camel-yaml"

The iconThemes contribution point is designed to replace the entire file icon theme in VS Code, not to augment the existing theme with specific file icons. When a user selects the "Karavan" icon theme, all file icons will be replaced with this theme's definitions, and only files matching ".camel.yaml" and ".camel.yml" will have icons - all other files will have no icons.

The correct approach for adding custom icons for specific file extensions is to use the contributes.icons contribution point combined with contributes.languages or file associations. Alternatively, consider using the approach of declaring file icon associations as part of the language definition if you have language support for these files.
