Can not find html file with report

I am having an error on running an app producing an HTML report. Please find the trace below. The report is produced to
URI:file:/D:/NetBeansProjects/EzLedger/target/Ezledger/VAADIN/themes/mytheme/CheckPayment_2019111820643.html
Hola Mundo 447 D:\NetBeansProjects\EzLedger\target\Ezledger/CheckPayment_2019111820643.html file:/D:/NetBeansProjects/EzLedger/target/Ezledger/VAADIN/themes/mytheme/CheckPayment_2019111820643.html file:/C:/Program Files/Apache Software Foundation/Tomcat 8.5/bin/CheckPayment_2019111820643.html

The information produced by the application when being executed is the following. It seems is missing part of the path to retrieve the report

Thanks. Changing the exporter resolved the matter
