Error retrieving file ' ': URL has an invalid signature.

AppSheet AppSheet Q&A

Does anyone have a solution for this? I do have the “options - **Require Image and File URL Signing”**enabled. I just need a link to be created that will allow for attachment viewing outside the app.

When I use this expression on my virtual column:

CONCATENATE(

“https://www.appsheet.com/template/gettablefileurl”,

“?appName=”, ENCODEURL(CONTEXT(“AppName”)),

“&tableName=”, ENCODEURL(“Estimates”),

“&fileName=”, ENCODEURL(CONCATENATE(“Attachments/Estimate_”, [Estimate ID], “.pdf”))

)

It generates the link:

https://www.appsheet.com/template/gettablefileurl?appName=fieldkrow-559301010&tableName=Estimates&fileName=Attachments%2FEstimate_d9938040.pdf

However, when I view the link, I get the error:

Error retrieving file ‘Attachments/Estimate_d9938040.pdf’: URL has an invalid signature.

Any help would be greatly appreciated. Thank you!

Yeah, not helpful that the doc shows the wrong setting.
