Swimlanes query issue

[Josipa Điri]

I want to add swimlanes on a sprint board board by field called Booking code. That is a number only free entry field.

I don't understand why I get the green checkmark as if the syntax is ok, but still the error with the operator "=". I tried different combinations and I still get this error.

When I try to add the query I get this error:

When I try to do the same with a different field it works, but that the other field has a drop down menu and not a free entry field.

Does someone know what is this about? 

Thanks!

Hi @Josipa Điri welcome to the community.  Change your syntax to a ~ instead of a = 

"Booking code" ~ "22088"

What is the precise custom field type of "Booking code"? If it is a single-line or multi-line text field, then you should try this:

"Booking code" = "22088"

can you check this syntax in an JQL issue search if is has the same error

can you try code IS 111

or code IN (111)
