Trouble attaching an array of pdfs to email

Attaching an array of PDF's to an email attachment

So in my flow I create multiple purchase orders in business central from a button I'm my powerbi report. For each PO I populate a word doc and save to one drive. Each one then gets converted to pdf and attached to an array. The flow moves onto an approval then a condition depending on the response. If yes I want to attach the array of PDF's to an email and send it.

The flow runs start to finish, the pdf's gets attached to email with the correct names. But there is an issue with the content. It is either corrupt and cant be opened or it is blank.

I have tried adding a delay in the flow but this has made no difference.

Can this be done? Where am I going wring?

Ai sends me circles of contradiction
