Generated an empty chunk: "index"

[fletcherbravo]

Does anyone know how to resolve this please?

Building app for Fitbit Versa

Building companion

Generated an empty chunk: "index"

Error: Compile failed.

Build failed.

Sorry, this is the full error message when hitting run in the watch face app.

It usually means that an expected source code file didn't have any code in it. If app/index.js and/or companion/index.js is basically empty, try putting something like

console.log('Running!');

in them.

Thank you, that worked but now its throwing up error 22 and error 2

My widget.gui and index.gui are both are both empty

Apologies this is all mew to me.

At this stage, you might find it easier by not starting from an empty project. I think that Studio and CLI both provide the option to start with a minimal working project. That would let you study what needs to be where.

Thanks, i'm using the digital watch face project but it's just not playing ball. I've followed the instructions but no joy. I'll keep trying.

SDK 4.3, I assume?

[fletcherbravo]

yes on a versa 

[Gondwana]

Maybe the penny has dropped, for me. Does your Studio (I assume) project contain a 'widget.defs' file?

[fletcherbravo]

yes it does

[fletcherbravo]

<svg>
<defs>
<link rel="stylesheet" href="styles.css" />
<link rel="import" href="/mnt/sysassets/system_widget.defs" />
</defs>
</svg>

[Gondwana · Accepted solution]

I think that what's happening is that Studio doesn't do a very thorough job when a default SDK5/6 project is converted to a SDK 4.3 project.

The breaking changes are described here. That doc assumes you're going from SDK 4.3 to 5; since you're going the opposite direction, those changes need to go the other way.

At a guess, try this:

• Rename widget.defs to widgets.gui
• In widgets.gui, change system_widget.defs to widgets_common.gui
• Rename index.view to index.gui

Don't worry; it gets easier after this!

Thank you, that's done the trick

Thank you Peter, much appreciated 🙂

Thanks Peter

I also had to edit package.json to remove some build types that got inserted.  To do this I changed the name to package.txt made my edits  and then names it back to package.json
