Using Multiple Attachment Controls within the V2 Trigger

Posted on by LosE

Hello,

I am creating an App that allows me to upload 8 attachments at the same time. The 8 attachments are inputted using 8 seperate attachment controls. I want to do this because so that i can then segregate each attachment without relying on the name of the attachement being correct.

When I create my "OnSelect" formula for my button in PowerApps it works with one file input. When i try to have two from two diffrent attachemnt controls it gives the error "Your formula is missing a column "contentBytes" with a type of "Blob".

Please advise if what im trying to do is possible or if there is a better way?

Using Multiple Attachment Controls within the V2 Trigger

Something weird is going on here for me. I copied your syntax which power apps was happy with. But then all of a suddent Power Automate starts giving me a "permission denied" error...

I then delete the second file I want to use and power automate is happy again... Any ideas?

SOLVED IT!

I removed the "{file:" and the last "}" from each file input and now it works!

My "OnSelect" code now appears as per below:

Thanks @WarrenBelz, unfortunatley the error persits. Appreciate any other thoughts on this.

The error shows for every file input. If i only have one file input the error disappears.

Many thanks,

Hi @LosE ,

Try using file: on them all rather than file_x:
