When using Chrome 70.0.3538.77 to catalog GUI , If the form is using lookup field do search and pull back the search result to populate other fields on form , a tab space ( \t) is being added after the value are returning on the form. It is invisible in GUI . But because invisible \t is part of the field's value there , if you read the value of fields on the form , for example in your PAM process , it can cause the issue because it looks like the value in the field is string 'abc' , but it is actually 'abc\t'
It is an issue caused by Chrome browser's bug in Chrome V70 version , and this Chrome browser bug was recognized and then addressed by Chrome Development later :
catalog 14.1 , catalog 17.1
Have your end users update the Chrome browser on their desktops to later or latest version .
Have your catalog server updated to catalog 17.2 version and apply the 17.2 maintenance patch on top of catalog 17.2 version . Although it is a bug with Chrome 70.0.3538.77 version, ITSM catalog development made the effort to trim off those additional & invisible tab ( i.e \t) which are added by Chrome browser V70 version's bug when pulling back the lookup fields result to populate other fields . This change is in the maintenance patch on top of catalog 17.2 version , and the versions forward .
Catalog 17.2 is available by the end of March 2019 . Its maintenance patch will be available shortly after it also .
