Building library - error

[smlkdev]

I tried to build library from the source code to debug it (npm link library to my app):

➜  comfyui-sdk git:(main) ✗ npm run build

> @saintno/comfyui-sdk@0.2.39 build
> bun build.ts

Bun v1.1.42 (macOS x64)

It compiled code (.cjs.js, .esm.js, .map) to build dir but without typescript definitions.

I use BunJS to compile the project, please install and use bun run build.

For me narrowing type by using instanceof does not work.

When I switch from:

comfyui-sdk/src/client.ts

Lines 510 to 514 in c84eadf

	if (file instanceof Buffer) {
	formData.append("image", new Blob([file]), fileName);
	} else {
	formData.append("image", file, fileName);
	}

to:

if (file instanceof Blob) {
  formData.append("image", file, "mask.png");
} else {
  formData.append("image", new Blob([file]), "mask.png");
}

it compiles fine

npm run build

I tried to find out why this happens, but I couldn't find an answer.
