InvalidPathException when create REST service from openapi.json using camel-karavan VS Code

[rapetum228]

Hello, I want to create a REST service based on OpenApi json. I use camel-karavan VS Code. Right-click on the file with openapi schema, select "Karavan: Generate REST API".

Regardless of whether I create a new integration or add to an existing one. Also regardless of whether I try to create just a REST service or a REST service with routes, this InvalidPathException error pops up. Can you suggest what to do?

What version of Karavan / Camel are you using? We have fixed some windows path issues with jbang in Camel 4.3

[rapetum228]

I'm using version 4.3.

[davsclaus]

Try with the new 4.4.0 release

@mgubaidullin it may be that karavan should execute this command with single quotes, for the input and output parameters for windows users:

camel generate rest --input='c:\Users\User\Desktop\Karavan1\event-gateway.json' --output=`c:\somedir\code3.yaml`
