Failed to run the MergeYaml recipe in Moderne CLI

[fcebk17]

What version of OpenRewrite are you using?

I am using

• Moderne CLI 3.26.2

How are you running OpenRewrite?

I want to add snippets to application.yml. Below is the command I use in Moderne CLI.

mod run . --recipe MergeYaml --recipe-option "key=$.server.servlet" --recipe-option "yaml='application-display-name:"application"'"

What is the smallest, simplest way to reproduce the problem?

server:
  port: 8080
  servlet:
    context-path: /api

What did you expect to see?

server:
  port: 8080
  servlet:
    context-path: /api
    application-display-name: application

What did you see instead?

server:
  port: 8080
  servlet:
    context-path: /api

What is the full stack trace of any errors you encountered?

popocorn@popocorn:~/output/AdminService$ mod run . --recipe MergeYaml --recipe-option "key=$.server.servlet" --recipe-option "yaml='application-display-name:"application"'"
