Unable to exec npx commands since Node-Red update

Hello,

I had an exec node that calls npm run tydom-client some other params
I worked well until I upgraded Node-Red from version 3.0.x to version 3.1.x. But now it runs indefinitely.

I saw nothing special when displaying TRACE logs.

Do someone know what could have changed in Node-Red that makes my exec node running indefinitely?

Thanks
