Hi,

If you are talking about what you are receiving after the implementation of Vadim's UDA, it sounds like you are not supplying a correctly formatted url to the Base64 object call. I would check out what you have as the Attachment URL.

I have implemented this and it works a treat. Thanks Vadim!

Regards,

Mark

Re: Get List Item Attachment in Base64  action for nintex forms

I have used foreach loop and in Attachment_url, I am getting url of one file (for example, http://abc/sites/sitecoll/Lists/Service​ TL/Attachments/805/call web service.txt)

While showing previous attachment in next task form, url of attachment contains additional part of task form url(for example: http:/abc/sites/sitecoll/Lists/Service%20TL/%7Bhttp://abc/sites/sitecoll/Lists/Service​ TL/Attachments/805/call web service.txt).

Here," http:/abc/sites/sitecoll/Lists/Service%20TL/%7B " is additional to my link.Because of this additional link  I am getting above error.

Please help me in this.

I guess you have attached the files on the new task via the workflow.

Can you explain how you did that ?
