Hi,
we kindly request that you add the following property to the "jasperreport.properties" file, located at Path: \apache-tomcat\webapps\jasperserver-pro\WEB-INF\classes\jasperreport.properties."
net.sf.jasperreports.chrome.tempdir.path=C:\\Program Files\\Apache Software Foundation\\apache-tomcat-8.5.77\\chrometemp
This approach ensures that the files used for Chrome rendering are not deleted during a clean restart (i.e., when the tmp folder is removed).
Thank you!
