ReportHello,
I am trying to create a flow that automatically sends an email including attachments when a Survey123 form is submitted. Here is the documentation from ESRI (Survey123's company) that I have been following:
Here are the steps in my flow:
However, like many other users responding to the thread, I am also getting an error: "Unable to process template language expressions in action 'Append_to_array_variable' inputs at line '0' and column '0': 'The template language expression 'base64ToBinary (body('HTTP').$content)' cannot be evaluated because property '$content' doesn't exist, available properties are 'error'. Please see https://aka.ms/logicexpressions for usage details.'."
Some tests I've tried is to use GET instead of POST in the HTTP action, I've started from scratch, I've tried testing step by step. Most recently when I try to run tests, the flow doesn't even complete, it just kind of spins. I've also tried running it live, but get neither completion confirmation nor any errors. I don't have a lot of experience with MS Power Automate (I could never have figured this out without that walkthrough), so any help would be greatly appreciated!
