The Azure OpenAI API always returns 'BadRequest: Invalid image data.' regardless of how the image is input, even if I don't change anything.
I also tested it on the Chat Playground in Azure AI Foundry, but it still returned 'BadRequest: Invalid image data.' I tried different models, including 4o, 4o mini, o4-mini, o3, 4.1-nano, and 4.1-mini, but none of them were able to process images. All returned 'BadRequest: Invalid image data,' even when using the image provided in Azure's documentation.

I understand that you're encountering an issue with the error 'Bad Request: Invalid image data' typically occurs when you provide invalid image data. Supported formats are primarily .png and .jpg, with partial support for static. gifs. This error can also arise from misconfiguration when sending image data to the endpoint. We usually perform base64 conversion for local images. Could you please provide me with a sample code.
Can you please refer the link https://learn.microsoft.com/en-us/azure/ai-services/openai/gpt-v-quickstart?tabs=command-line%2Ckeyless%2Ctypescript-keyless&pivots=programming-language-python
Hope these helps you. Thank you.

2025-06-12T04:30:12.61+00:00 I think is Azure OpenAI Server issues on that day, because after a few hours on that day, it became normal, but I didn't find any problems on the statement page.
