Code 404 for sending requests with images (stored in Google Storage)

[IagoRabelo]

Description of the bug:

I'm having trouble sending requests to analyze images hosted on Google Storage. Today my application already works with sending images converted to base64, however, when switching to the hosted image link, I encounter a 404 error.

Actual vs expected behavior:

My application currently works using the @google/generative-ai lib and the following methods:
`
const chatSession = model.startChat({
generationConfig,
history: context,
})

const resp = await chatSession.sendMessage(["Perform the analysis and answer the questions in the json format provided"])
`

It is currently working with a context in this format:
[ { "role": "user", "parts": [ { "text": "OCR_NF: [\nOCR reading content\n]" }, { "inlineData": { "data": "iVBORw0K....kJggg==", "mimeType": "image/png" } } ] } ]
However, now, changing it to read the file from Google Storage, it looks like this:
[ { "role": "user", "parts": [ { "text": "OCR_DOC: [\nOCR reading content\n]" }, { "fileData": { "fileUri": "gs://bucket_name/file_name.png", "mimeType": "image/png" } } ] } ]
However, the response is always a 404 code:
{ "response": { "status": 400, "statusText": "Bad Request" }, "verify": false }
Observations:

1. The files are being saved correctly;
2. The link was checked and is correct;
3. It is within the same Gemini project;
4. To save the file I am using the @google-cloud/storage lib with the methods: storage.bucket, bucket.upload;

First time posting here, I hope I was clear enough.

Any other information you'd like to share?
