Cannot run program "npx" error=2, No such file or directory

[debraj-manna]

I am trying to use frontend-maven-plugin 1.12.1 with maven 3.8.4. My pom configuration looks like below. But on doing mvn clean install I am getting the below error

Error:  Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.1.0:exec (validate api specs) on project master: Command execution failed.: Cannot run program "npx" (in directory "/opt/actions-runner/_work/spotnana/spotnana/src/java/obt/master/target"): error=2, No such file or directory -> [Help 1]
Error:  

Can someone let me know what I am doing wrong?
