PDF Service API ServiceApiException....The zip file provided has invalid content. statusCode=400

[Simran Inamdar]

I am able to run the sample project. I have created another zip archive of HTML file and other dependency files like CSS and js and pass it to the CreatePDFFromDynamicHTML.java file to create a PDF after executing

 mvn -f pom.xml exec:java -Dexec.mainClass=com.adobe.pdfservices.operation.samples.createpdf.CreatePDFFromDynamicHTML command it gives an error 

description ='The zip file provided has invalid content.; transactionId=kNWylwnmtNDbJf9ERkbjuE1Ou62467uv'; requestTrackingId='ZDdG1zgw5sKjMdnEGjvV8PAdUlJwwwNO'; statusCode=400; errorCode=INVALID_ZIP

How to resolve this?
