How to pass uploaded image from Form Trigger to LLaVA/Ollama?

Hey everyone! Quick question - I’m trying to send an image from Form Trigger to my self-hosted LLaVA (on Ollama/Railway) for OCR, but I can’t figure out how to get the binary data to actually reach the vision model. The form captures the file metadata fine, but when I try to extract the binary with item.binary[key].data.toString('base64') and send it to Ollama’s /api/generate endpoint, LLaVA doesn’t seem to “see” the image. Should I be using AI Agent nodes or just HTTP Request? Has anyone got Form uploads working with vision models? Thanks! :folded_hands:

Hi @Kaouthar_Bousbaa ,

Use HTTP Request Node

Your workflow should be like this;

Form Trigger → Code Node (prepare image) → HTTP Request (to Ollama)

Hi @Kaouthar_Bousbaa,

Why dont you just use the Ollama node for this. Connect your auth to the Ollama instance you have and then use the analyze image with the llava model selected?
