Using Power Automate to attach different file types

[Hammers211]

I am struggling with making a particular Power Automate flow. Here is what I would like:

1. Survey response is submitted with a file attachment, a photo, and an email address

2. An email with attachments is sent in response to the survey submission. The attachments are the file attachment and photo.

I am able to create a flow that will send one or the other, but not both. I think the issue is that I am not setting the dynamic content for the file contents correctly. When I set up the flow for sending just one item, I am able to select "Body" for the file contents, and the flow functions as expected. When I try to add the second attachment, I am not able to select "Body" for the file contents. The flow does create two attachments, however the second is always a corrupt file. Thanks for any help!

Are you initializing an array with your photos and then adding the array variable to your email?

[Hammers211]

No, not at this point. If I will only have 1 image and 1 file, is it possible to do it without an array?

[TL2]

No, but its also fine for an array to have one item.

I have figured out how to initialize, append, and attach a single variable to an email, but when I try to repeat the process for a second variable, I am getting an error:

Flow save failed with code 'InvalidTemplate' and message 'The template validation failed: 'The inputs of template action 'Append_to_array_variable_2' at line '1 and column '2797' cannot reference action 'HTTP'. Action 'HTTP' must either be in 'runAfter' path or within a scope action on the 'runAfter' path of action 'Append_to_array_variable_2', or be a Trigger.'.'.

Any help on doing with with the second variable?
