Error spawn uvx ENOENT

[icyvapor]

Hello,

I'm having trouble starting AWS API MCP Server.
I'm in a VS Code dev container, where I've installed uv and uvx. Verified this by running 'uvx' on commandline.

Installed AWS API MCP Server by clicking on the 'Install | VS Code' button, on the main page.
(link: https://insiders.vscode.dev/redirect/mcp/install?name=AWS%20API%20MCP%20Server&config=%7B%22command%22%3A%22uvx%22%2C%22args%22%3A%5B%22awslabs.aws-api-mcp-server%40latest%22%5D%2C%22env%22%3A%7B%22AWS_REGION%22%3A%22us-east-1%22%7D%2C%22type%22%3A%22stdio%22%7D)

Then in VS code under 'Extentions', I see 'AWS API MCP Server' appears under "MCP Servers - installed". But trying to start the server always give me following error:

2025-08-18 19:30:13.074 [info] Starting server AWS API MCP Server
2025-08-18 19:30:13.076 [info] Connection state: Starting

2025-08-18 19:30:13.087 [info] Connection state: Error spawn uvx ENOENT

What am I missing?

Thanks a lot!
