base64toBinary, unable to process template language expression

[StijnDekimpe]

HI

I'm made attachments in power app store the files and pictures directly to a dedicated library.

This has worked fine for months but stopped working a few months ago. didn't get any notification so can't tell exactly when.

Error in automate

Coding in power apps

Set(varAttachmentControl, JSON(ImageAttachment.Image, JSONFormat.IncludeBinaryData));

Set(varBase64only, Mid(varAttachmentControl, Find(",", varAttachmentControl)+1,Len(varAttachmentControl)- Find(",", varAttachmentControl)-1));

Set(varFileLink, UPloadtoSharepointfrompowerapps.Run(Last(AttachmentControl.Attachments).Name, varBase64only).sharepointfilelink);

Reset(AttachmentControl)

flow

also I respond back to power apps but I'm blocked on where and how to store that info?

thanks
