perf-postprocess error with field count in SPR CPU

I recently successfully gathered perf stat csv with perf-collect command.
And tried to use perf-postprocess command to generate metric out csv and html files but it failed with following error.
Traceback (most recent call last):

I compared the output file of perf-collect file with ICX CPU files and found that the field count of ICX csv file was 8 but the field count of SPR csv file was 10. Plz check and let me know how to fix it. Thanks.
could you please include your OS, kernel version and perf version?
Hi,
OS : CentOS Stream release 9
Kernel : 5.14.0-283.el9.x86_64
Perf : perf version 5.14.0-283.el9.x86_64
I also retested with perf version 6.1.rc2.gb229b6ca5abb and got same results.
Hi, today I found my mistake of dealing with latest perfspect.
I got error when I use older version of perf-collect and latest version of perf-postprocess.
I was able to get the desired result by deleting the old version of the perf-collect file and retesting with the latest version.
Glad the recent version worked for you!
