ODK Scan Form Designer TAB - Save to File System Error

Hello Everyone,

I have designed the ODK Scan form. When I go to File -> Save to File System, it gives me the following error.

“TypeError: base64.decode is not a function”.

I am using the ODK X Application Designer v2.1.6.

I have tried it both on Windows 7 and 10. Same problem exists.

Here’s the log
TypeError: base64.decode is not a function
at postHandler (C:\Application Designer\app-designer-2.1.6\Gruntfile.js:56:29)
at call (C:\Application Designer\app-designer-2.1.6\node_modules\connect\index.js:239:7)

at Server.emit (events.js:315:20)

at HTTPParser.parserOnHeadersComplete (_http_common.js:116:17)

Can someone please help me in the exception that I am getting listed above.

Hi @araza,

I have not seen this error before, but my guess is its a bug in the Scan Form Designer tab and probably not a bug in your form.

Are you able to save any artifacts that I can use to try to reproduce the problem? Or at least could you take a screenshot of your form or describe the elements you added?

Regards,
Jeff

Hi Jeff,

Thank you for your response. Yes I have got a form that I can send over. I’ll attach it over here. You can load it as incomplete form in the’Scan Form Designer’ tab.

Hi Jeff,

Have you been able to reproduce the error that I was getting. I hope the zip file that I have sent is working.
