glide_list isn't populates with sys_id iva Flow Designer after Xanadu upgrade

[sharepointau]

We have a flow that collects an array of sys_user sys_ids and sets a glide_list column in a table via flow designer. This has been working for about 3 years and is still working in production; which is Vancouver. 

Recently, we upgraded our non-production to Xanadu, and this flow is now populating the glide_list with the actual array and not the records the sys_id references. 

1. Prod Vancouver been working for 3 years populating the glide_list with the actual user records via array of sys_ids.

2. Non-Prod Xanadu populates the same glide_list with a string version of the array of sys_ids

Has anyone seen this, or has a suggestion on how to populate a glide_list via flow designer with actual records?

@sharepointau 

share how you are fetching the sysIds array?

Seems the way how it's fetched is impacting when compared to Instance

If my response helped please mark it correct and close the thread so that it benefits future readers.

Thank you for your quick response. I have tried a few different ways from where I started, but I will share the original first. They all ended the same with just the array in string form instead of the records in the glide_list (screenshot below).
