Transform Functions not working in Flow Designer on Customers Instance - How do I enable them ?

Hi ServiceNow Community,

For some reason, I am unable to select Transform Functions, on my customer's instance that I am working in.

I am in Flow Designer and trying to click on the fx button, but the window that loads the Transform Functions, just does not load/pop up. This works perfectly in my PDI but not in the customer's instance.

Please see my screenshots attached.

Is there a place I have to go, to enable the Transform Functions so that they work in Flow Designer, or is there some setting I need to validate, as I do not understand why these are not loading, but yet they work fine in a PDI.

I would appreciate any help/guidance/advice on where to check.

Many thanks.

@Elijah Aromola @daniellebell @Ankur Bawiskar Hi everyone. I wanted to share you the steps to help with a solution here. We logged a HI Portal request and indeed, it turns out this is a known issue. ServiceNow have provided a solution, in order to resolve this on Vancouver, here is what ServiceNow advised:

Issue:
Transform map function on flow designer is not loading for If/else if condition.

Most Probable Cause:
We have identified this issue due to a platform defect, "PRB1705741," which is affecting Vancouver Patch 2, Vancouver Patch 3, and Vancouver Patch 4.

Solution Proposed:
The issue is already fixed in the Vancouver Patch 5 version.
*The Vancouver Patch 5 version is already released and available for upgrade, please upgrade you instance to Vancouver Patch 5 to get the fix for the defect.
Currently, there is no workaround available for this issue.

@daniellebell thanks very much Danielle, good to hear that I am not alone in this. Yes funnily enough, the customer has just two weeks ago upgraded to Vancouver, so I guess the issue is related.

It is exactly the same for me - it is occurring when I try to use (Fx) within or under If Conditions - this is exactly what I am finding.

Thanks for the suggestion about using Flow Variables, perhaps I can try this too. The only issue/not sure how I could get around this - I need to use an If function, in cases where the field entry that comes back from my 'Make a Decsion' table/function, leaves out results where IsNull = True, hence why I need to use If IsNull = True, as I don't want to trigger a Catalog Task, where there are blank entries in the 'Make a Decision' Approval table

I am really finding it hard to find a solution where I can use Flow Variables and filter out IsNull entries, which are driven off my 'Make a Decision' action/table. That is my challenge now, without being able to use Transform Functions.

Thanks so much for feeding back on this, much appreciated.
