Cannot read property 'toLowerCase' of undefined while searching

[pniedzwiedzinski]

As I used search function this error occurred:

> /search PRDev
/usr/local/lib/node_modules/fb-messenger-cli/lib/search.js:49
            return friend.name.toLowerCase().indexOf(searchString.toLowerCase()) !== -1;
                               ^

I have the same issue.

No conversations appear on the first screen, selecting any number gives the error;

Warning: Input is out of bounds

Actually I solved this issue for me(Arch Linux). You need correct version of node.js. Error occured when I used 10 but when I downgraded to 7 it worked.

Same on Windows 10 with Powershell, downgrading npm to 7 change nothing for me. Does it even work on Windows 10 ?

It should work we developed on Win10, perhaps you would have better luck with cmd. At some point I should have some free time to address the root cause.

The same problem with windows 10 and cmd

Okay I removed .kryptonite in AppData\Roaming\npm\node_modules\fb-messenger-cli and now it works.
