What's the syntax for "other attachments" in a scheduled report?

[Rosemary_Black]

I am using a concatenation to refer to a file attachment that was saved in another workflow, saved on Drive, in the default folder for the app.

CONCATENATE(“Files/”,(RIGHT(YEAR(NOW()),4)),IF(MONTH(TODAY())<10,CONCATENATE(0,MONTH(TODAY())),MONTH(TODAY())),IF(DAY(TODAY())<10,CONCATENATE(0,DAY(TODAY())),DAY(TODAY())),Daily_Warning,".csv")

Which results in:

Files/20190327Daily_Warning.csv

But I can’t get the report to find the file. Is it the syntax that is wrong?

I am not certain I understand. Are you saying that the file you are trying to attach to the Report email was uploaded by the AppSheet application via a File field?

File created from another report.

Report 1 - Creates csv from template with the concatenated name.
Report 2 - 10 minutes later emails out the csv created.

The file is named correctly, and in the right folder, I just get the error when report 2 triggers:
“Errors”: “Error: Workflow attachment file ‘Files/20190327Daily_Warning.csv’ not found due to: Object reference not set to an instance of an object…”,

I have tried referring to this file in the “other attachments” of report 2 in many different ways, I’m not sure how to get the report to find this file.

Ideas?

See topic " Constructing an Attachment File URL" in this article https://help.appsheet.com/behavior/workflow-sending-email/email-pdf-attachment-archiving

Using that format, I can get a url to download the file, but it isn’t as a .csv anymore, and it isn’t named. This also doesn’t let me attach it to the email as a file. I didn’t expect this to be so hard lol

I got it to work in a different way! No report 1, just an email using the csv template for the attachment, and making the attachment name end in .csv wow, thank you for your help.
