empty report issue

We installed Intel Quartus 19.2 and Intel FPGA SDK for OpenCL version 19.4 for the D5005 acceleration card. When we tried to compile the example vectorAdd openCL kernel code with aoc -rtl vector_add.cl -report (or aoc -o vector_add.aocx vector_add.cl -report), we alway get empty report at vector_add/reports/report.html. Could you please advise?

Here is my running env
