I have a Hyperlink or Picture column in sharepoint online list named "Document Link" I am creating a flow where I need to check a condition if this column is empty or null. I have tried few things but while using Get Items action the action is not giving result DocumentLink=null if it is empty. It is gives the values if it is not null and hence I am not able to check the empty condition against it.
it will return JSON collection with null values too (see in next picture) of Items (or if you use item(id) in HTTP request URI > return only 1 item)
after this you just need Parse JSON action and after this work with the properties from it.
Hope it helps!
