I'm getting a `runtime error: index out of range [0] with length 0` after authentication

Hi @jonathanlaniado

I can't reproduce this, so I will need your help to get more information about what's happening.

Could you open the Alfred preferences, go to Workflows, and click the bug icon in the top right corner to show the debug console, and then do what gave you this error again, and copy what you got in the console and send that?

[jonathanlaniado]

Hmm one thing I can identify is Line 3 here, where the argument appears to be null.

I also notice it's referencing your user account (/Users/andreas/) several times. Is that typical?

Anything else I may be missing?

Thanks!

Which version of Alfred are you using?

It's referencing the paths where these files where when they where compiled on my computer (it's not anything it tries to find on your computer), so that in itself should not be a problem.

I will look more into it and try to find a solution. Probably tomorrow.

Thanks for reporting this!

[jonathanlaniado]

Thanks, appreciate it. Looks like 4.5.1!

(forgot to add – MacBook Air M1, latest Alfred, 4.5.1)

[westerlind]

Thanks for reporting @vladstudio

I have an M1 MacBook Air too, so it should work there for sure. I'll look more into it later today, and will probably be able to fix it.

[westerlind]

Hi @vladstudio and @jonathanlaniado

I have figured out what the problem was!

It turns out that all my own collections in Raindrop have manually set icons on them, so I had missed that my check for if there was an icon set or not wasn't functioning properly, so if you had at least one collection that you had not set an icon for (which would have the generic folder icon), you would get this error.

I have released an updated version (2.0.4) that fixes this.

[jonathanlaniado]

Fantastic, Andreas, that fixed it for me. Awesome work pinpointing the issue and thanks for the speedy help!
