Add atachments from other Flow - action

0

I try to add attachments from other flow using standard Action add attachment ...
in theory is working:

https://community.webcon.com/posts/post/the-add-attachment-action/156/18
or
https://docs.webcon.com/docs/2023R3/Studio/Action/Attachments/Action_AddAttachment

but not in my case :/ and I don't know why ...

"Wystąpił błąd wykonania akcji Dodaj załącznik na przycisk w menu.
Błąd wykonania akcji typu dodaj załącznik: Dodaj załącznik.
Object reference not set to an instance of an object."

the flow ID from where I would lite copy attachments is = 20008

I try use tech_filed set as text or drop down list ... and all time failure
if in tech field I have "20008"
then "Object reference not set to an instance of an object."

if I have signature of flow "ZAM/2024/03/00188"
then "The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction."

if I do SQL
SELECT [ATT_ID] FROM [WFDataAttachmets] where ATT_WFDID='{2592}'
and in test field is "20008" then I see in designer 4 attachments

but in action from (menu button) -> error .. the same



(in theory maybe what I need) [how to find in flow ID of Attachment ? ]
-edit --
>> SELECT * FROM [WFDataAttachmets] where ATT_WFDID='{2592}'
OK I have what I looking for [in design studio] , but ... action is not working in flow :/ (gives error)

What I'm missing ?

btw:
I do continuation from that topic:
https://community.webcon.com/forum/thread/4702

I have all data, added Item list ... just attachments left :/
