I have played around with various pipes and got them to work and I tested the tag gun pipe and it works in test mode.
I created a two-step form and step one scans the image and record rules are supposed to populate a field with the URL of the image so I can submit it to TAG GUN in step 2. I followed this post Creating a pipe to get the URL of image fields but I can not get it to insert ANYTHING into the URL field. So on step 2 the URL field is still blank so I have nothing to submit to TAG GUN. I tried formatting the IMAGE URL field as a Link and also tried text. but neither helped. I tested a simple record rule update the URL with the custom text “Hello World” and that worked. I also tried a simpler pipe but to no avail, so whatever I am doing with the pipe is not working.
