Just got the same error

[mintmcqueen]

same...seems like it has to do with git versioning -- image read was working fine until i made my first commits.

[markbastian]

I've been stuck on this for at least a week. If I convert an image to a grayscale gif it works. Very kludgy, though.

[dicksontsai]

Thanks for the report, everyone. I will look into it and report back if I find a fix.

[Peddle]

FWIW i'm getting this same error on an Ubuntu 25.04 Arm VM running on an M1 Mac.

Interestingly making the image file size smaller seems to work. I had claude code try converting to grayscale as well as reduce the resolution and found the following:

as a work around i've just added a preprocessing step that compresses images before claude code reads them

[dicksontsai]

This turns out to be a dependency/platform issue. I have a fix that I am aiming to deploy in the next release or release after. In the meantime, you can indeed avoid this issue by compressing your images before Claude Code reads them, though I understand if it is very inconvenient.

[dicksontsai]

Please update to v1.0.8, which addresses this issue.

[Vasanth-070]

@dicksontsai iam on 1.0.30 (Claude Code). still getting the same error.

[dicksontsai]

@Vasanth-070 which platform are you using? Did you install through npm or some other way?

[Vasanth-070]

Hi thanks for the reply. Iam using mac os 15.5. i have installed claude code via npm.

Hi, same issue here. I'm running Claude code v1.0.31 on WSL: 2.5.9.0. Getting the same error when pasting an image to the console:

Error: (B.default || B) is not a function

[KiichiSugihara]

I ran into the same bug. Just to share — it looks like when you drag and drop an image directly from Finder (or another file manager) into the terminal, the image gets recognized correctly. This seems to work.

As a side note, it doesn’t work if you’re using the VS Code extension — drag and drop doesn’t seem to be supported there.

Also, when passing an image path directly, I get the same error as before. I’m not entirely sure how it works internally, but manually dropping the image seems to let it read the data correctly.

Hope this helps as a temporary workaround.

[SpaceDandy13]

@dicksontsai got the same error in 1.0.38 (Claude Code) on WSL: 2.5.9.0. Installed via npm.
