Doesn't work inside azure function

[akay0214]

const { compare } = require("odiff-bin");

const httpTrigger: AzureFunction = async function (context: Context, req: HttpRequest): Promise<void> {
    const actual = (req.query.actual || (req.body && req.body.actual));
    const expected = (req.query.expected || (req.body && req.body.expected));

    if (actual && expected) {
        try {
            temp.track();

            const actualPath = temp.path({ suffix: '.png' });
            await downloadFileFromUrl(actual, actualPath);

            const expectedPath = temp.path({ suffix: '.png' });
            await downloadFileFromUrl(expected, expectedPath);

            const { match, reason, diffPercentage } = await compare(
                actualPath,
                expectedPath
            );

            context.log(`Compare screenshots result: equal=${match}, reason="${reason}", diffPercentage=${diffPercentage}`)

            context.res = {
                body: {
                    equal: match,
                    reason,
                    diff: diffPercentage
                }
            };

        }
        catch (e) {
           context.log(`Error occured while comparing screenshots: ${e.message}`, e);     
        }
        finally {
            const cleanupResult = await temp.cleanup();
            context.log(`Cleaning up: files[${cleanupResult.files}], dirs[${cleanupResult.dirs}]`);
        }
    }
};

Error:

Error occured while comparing screenshots: Error at ChildProcess. (C:\home\site\wwwroot\node_modules\odiff-bin\odiff.js:134:13) at ChildProcess.emit (events.js:327:22) at maybeClose (internal/child_process.js:1048:16) at Socket. (internal/child_process.js:439:11) at Socket.emit (events.js:315:20) at Pipe. (net.js:673:12)

Any idea how to fix it?

Tried on both Linux and Windows. Same error everywhere. Works okay on my local env tho.
