Analyze Images - problem with binary input

Hi,
I’m trying to analyze an image with OpenAI “Analyze Images” module and I am getting this error: [400] You uploaded an unsupported image. Please make sure your image has of one the following formats: [‘png’, ‘jpeg’, ‘gif’, ‘webp’].

This is the setting I have

My input is an image file in binary. This is the output bundle of my first module (custom webhook):

[
{
“value”: “IMTBuffer(27, binary, b51f8257083bbc2a8ba3c86211d1e492df5cc204): 2f396a2f34414151536b5a4a526741424151454159414267414144”
}
]

How can I make the OpenAI module accept the binary data? I think there’s some problem with the data format, but I’m not sure what exactly is the problem and how I can solve it.

I’ll be grateful for any advice. Thank you!
