Cannot run flow via powerapps

[paulinuk]

Hello

I have the code below which tries to call a flow passing the image in an image control

Set(varImage, JSON(Image4.Image, JSONFormat.IncludeBinaryData));
Set(varBase64Only, Mid(varImage,Find(",",varImage) + 1, Len(varImage) - Find(",", varImage) - 1));
Set(varTest, SaveAttachment.Run(Last(addAttachment.Attachments).Name, varBase64Only).sharepointfileLink);

However, this comes up with a message saying number of arguments expected 0-1 receieved 2

This is copied directly from a video, but I guess that MS may have made a change since this was done

Please can someone help asap?

Cheers

Paul

Hi @paulinuk ,

Could you please provide some screenshots about your flow?

The Add Attachment Action should be as shown below:

Remember to refresh or re-add the connection, then try it again.

In addition, here is a similar case for your reference.
