Query failure while checking to create or update list item


I'm using a HTTP Request to add items to a SharePoint list. This is working fine.

Now I changed my flow to check if a list item already exists (then update) or not (then create)


This is a part of the flow:


I use the filter query to check if the record already exist.



Both fields Kandidaat ID and UniqueID are strings.


After running the flow this error appears:


I tried everything, incl brackets or sequence. It does not work. What am I doing wrong. Here also a snip of the create item step (which works fine without the condition and query)





Question 2: is the syntax i'm using to check if the result of the get items step the right one?



Thank you very much for your help.

Regards, Alex

@ALute - Can you put value of kandidate id in single quotes too? 'Kandidat ID' eq '123466' and then try?
