Entity with String field containing " (quotes) in value makes frontend produce error

[OmarHawk]

Assume we have an entity, that has a String field. The user saves a value that contains a quote character into the string field, e.g.

hello "Peter"

When trying to load the entity changes for that entity, the frontend produces an error like this and the list view does not work at all for that entity.

VM445:1 Uncaught SyntaxError: Expected ',' or '}' after property value in JSON at position 450 (line 1 column 451)
    at JSON.parse (<anonymous>)

This is because of the following:

generator-jhipster-entity-audit/generators/spring-boot-javers/templates/src/main/java/_package_/web/rest/dto/EntityAuditEvent.java.ejs

Lines 148 to 160 in 111e39a

	StringBuilder sb = new StringBuilder("{");
	for (String s:snapshot.getState().getPropertyNames()) {
	count++;
	Object propertyValue = snapshot.getPropertyValue(s);
	sb.append("\"" + s + "\": \"" + propertyValue + "\"");
	if (count < snapshot.getState().getPropertyNames().size()) {
	sb.append(",");
	}
	}
	sb.append("}");
	entityAuditEvent.setEntityValue(sb.toString());

-> The entity propertyValue is not being escaped properly.

Probably other characters like line breaks could pose the same issue.
