Getting handlebars prototype access error while testing our application.

See more:

ReactJS

Our project is a Maven project and we are getting the following warnings while regression testing:



Handlebars: Access has been denied to resolve the property "statements" because it is not an "own property" of its parent.



In the documentation I read it can be overridden using runtime options like,



const template = handlebars.compile("{{aString.trim}}");
const result = template({ aString: " abc " });
// result is empty, because trim is defined at String prototype
const template = handlebars.compile("{{aString.trim}}");
const result = template(
{ aString: " abc " },
{
allowedProtoMethods: {
trim: true
}
}
);
// result = 'abc'



But not sure where to implement.
As the Yarn is automatically configured in POM.xml I cannot add the package @handlebars/allow-prototype-access as we cannot use manual yarn commands for it.

What I have tried:

we tried degrading the version of handlebars. The dependabot alerts on github wants the version 4.7.7 or higher so that is also not a possibility.
Also we tried installing the handlebars@allow-prototype but that requires the lower version and since it is automatically cofigured to pom.xml we can't seem to run manual commands.
