Testing

I cloned a fresh repo from the release 1.7 and ran a default character with twitter client. My .env contained an Openai API key and I used a venice API model for my agent. I implemented the fix from this PR first PR 1667
After that, I added a printline to the requestOpenAI function inside of packages\plugin-node\src\services\image.ts at line 221 and 222. (file is not included in PR since it is not needed for the fix).

const responseText = await response.text();
//Line to verify if API is giving back an image description
elizaLogger.log("OpenAI Response Status:", response.status);
elizaLogger.log("OpenAI Raw Response:", responseText);

Where should a reviewer start?
