Frontend bug when displaying "Workflows (jobs in ReqMgr2)" in RelVals page

[francescobrivio]

When one tries to display the Relvals for a specific ticket, eg. with:
https://alcaval.web.cern.ch/relvals?ticket=CMSSW_13_0_7__CTPPSPixelGains-00001&shown=1111110000000000010110&limit=50&page=0&filter=
a blank page is shown.
Instead if one manages to de-select the Workflows (jobs in ReqMgr2) the url is upated to:
https://alcaval.web.cern.ch/relvals?ticket=CMSSW_13_0_7__CTPPSPixelGains-00001&shown=1010000000000000000000&limit=50&page=0&filter=
and the relvals are correctly shown.

Note the difference in the shown filter in the url:

• 1111110000000000010110 : not working
• 1010000000000000000000 : working

Additional note: all other selectable "Columns" work as expected.
The only one giving problem is Workflows (jobs in ReqMgr2) as mentioned above in the Issue description.
