venom: Error sendFile

I got this error and I couldn’t resolve it

erro: true, text: 'test', status: '', type: 'FileFromBase64', filename: 'a.pdf', mimeType: 'application/pdf'

I am using this code

await client.sendFile(number + '@c.us', filePath, fileName, caption);

I try to sendBase64 too, but I got the same error.

Someone can help me?
