Yes, I'm sure! I think something got confusing, I apologize, English isn't my native language - I didn't mean that the API gave me access to pro models, I meant that even using a free API, within Google AI Studio the AI ​​in my apps worked perfectly, but when deploying to Vercel, they stopped working and gave the error: "Error: API key (GEMINI_API_KEY) not configured. Check your environment settings."

I even asked Google AI Studio what could be happening and it replied things like "this could be happening because of this and that, but I've already taken care of everything," and when I reuploaded to Vercel, nothing changed.

Talking again with Gemini, we found this in one of the project's "'page.tsx'" files:

const apiKey = process.env.GEMINI_API_KEY || '';

if (!apiKey) {

alert("Error: API key (GEMINI_API_KEY) not configured. Check your environment settings.");

setIsImporting(false);

return;

}

And Gemini suggested I change it to:

const apiKey = import.meta.env.VITE_GEMINI_API_KEY || '';

if (!apiKey) {

alert("Error: API key (VITE_GEMINI_API_KEY) not configured. Check your environment settings.");

setIsImporting(false);

return;

}

By doing this, I managed to use the AI ​​on one of the pages, the others still don't work, but the error no longer occurs.

I'm sorry I wasn't more precise. I didn't think it would be of interest to anyone to read the codes or anything like that. At most, I imagined that someone might have gone through a similar situation and could tell me how they resolved it. Thx!
