It also lets me go through the steps of searching my computer, selecting the images and clicking open to begin the upload process. It even correctly identifies how many images I am ready to upload.
There’s a really useful tool to help work out what’s going on that I would recommend:
If you have saved and uploaded the file, when using your browser, use the Dev Tools (usually right-click on an object on the page and choose ‘inspect’). There is usually an option for ‘Network’ which will show you what connections are being made to send/receive data from the page to the Server Connect actions. As events are fired, this list will show you what is going on - that way you can tell if the page is firing the form to submit or whether the data isn’t being sent at all:
Check the button is within the form or you have a dynamic event to submit the form
Check the network dev tool to see what is being sent and what response it gets. That way you can tell whether it is the page or the Server Connect action that is the problem.
Here’s the place in the video where I apparently got the idea to put the brackets in.
It looks like some sort of array was being established. I’m not sure.
I have no idea whether or not this is what’s causing my issue.
From the error I see that there is something wrong with one of the expressions in your Server Connect action file. In the stacktrace I see that it is probably the Image Processor, something with a path /galleries/{{$_.... Could you provide a screenshot with the properties of that action step, I think it would be the Save Image step. Then I could check if the expression is wrong or that it may be a bug.
