You missed the most important part I need to see the value of the tag in step 4. Also, lets check one of the runs in the History to know what happened exactly. You better record a loom.
The last part of the video is where the error is it’s add to 3 different tags instead of 1 tag
Based on the video, it looks like the mapped data in the Filter step is missing from the Code step. When you see a yellow placeholder in a field, that typically means the data from the previous step isn’t available or didn’t come through properly.
I’d recommend remapping the Filter step with the correct output from the Code step to ensure everything is connected correctly.
