Can't add Dynamic Content inside HTML code for Email Body in Power Automate flow.

Greetings,

My email body has table and images. I converted the text, tables and images to HTML code and pasted into the 'body' section of 'Send an email (V2)' action node. I can 'save' the flow until this stage. When I add a Dynamic Content (/) inside the HTML body, the flow doesn't save the change, rather throws an error "The input parameter(s) of operation 'Apply_to_each' contains invalid expression(s). Fix invalid expression(s) for the input parameter(s) of operation 'Apply_to_each'."

The following screenshot shows the Dynamic Content "ORG_CODE" can easily be saved in the "Subject" field of the email, but when I want to insert the same Dynamic Content inside the email "Body" (which is all HTML code), the error message appears. I tried many options and searched for a solution in almost every related topic found online, but no luck yet.

Hi @VictorIvanidze,

Thanks a lot for your suggestions. In fact, I tried using the "Compose" action node before. After your suggestion, I tried again, and it shows the same error message as shown in the screenshot below,

Create a Compose action before Send an email and try to create the HTML email body there.

Hi @DJ_Jamba,

Thanks for the clue. I tried in 'Classic designer' also, it's the same when I add any Dynamic Content inside the HTML body, as shown in following screenshot,

Do you get the same error in the classic designer?
New designer is buggy as hell!

Hi Michael,

Thanks a lot for your prompt response. I used the Dynamic Content (i.e., "ORG_CODE") from "List rows present in a Table" node. This is the place where I have my required Dynamic items to pull from, as shown in the Screenshot below. It works fine in the "Subject" field, but not inside the "Body", specifically inside the HTML code.

Sincerely,

Moonem

Hi @MM-27032222-0

Hi, Is the property (both of them) from the Apply to Each or any chance you accidentally applied the one from the List Rows inside the body?

Not sure otherwise, how that would cause your Apply to Each to fail, never seen that.
