@SriRaghavendran Prabhakaran Thanks for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this.

In Append to Array variable action try adding another parameter with contentType as shown below in the similar thread here.

[{ "ContentType": "Content type", "ContentData": "Content data" }, { "ContentType": "Content type", "ContentData": "Content data" }]

@SriRaghavendran Prabhakaran

Thanks for your response, Error message states that passed ContentData is of type string instead of byte.

Also, as per documentation, smtp send email action allows ContentData type of byte only. Try converting the string content to byte using base64(<contentType>).

@SriRaghavendran Prabhakaran Thanks for your follow-up questions, apologize for the delay in my response over the weekend.

In the SMPT Send email actions change the type of Attachments to Switch to detail inputs for array item and pass the Array to Attachments variable as shown in below GIF.

Hope this helps, let me know if you have any further questions on this.
