=== How to fix "Request contains an invalid argument" ===
'''Error message'''
<pre>
無法提交提示
錯誤訊息：「Request contains an invalid argument.」

狀態：400 錯誤代碼：3

要求 ID：xxx
</pre>

'''Model Affected''': gemini-1.5-pro-preview-0409 or gemini-1.5-flash-preview-0514 

'''Workaround solution:''' 
* If you upload a video file for API analysis, you might consider shortening the video duration, for example, using ffmpeg to reduce an hour-long video to half its length. This will help reduce the input token length.

=== Resolving "Model not found for API version v1beta" Error with Gemini API ===

'''Error Details'''
<pre>
{
  "error" : {
    "code" : 404,
    "message" : "models/gemini-2.0-flash-exp-image is not found for API version v1beta, or is not supported for generateContent. Call ListModels to see the list of available models and their supported methods.",
    "status" : "NOT_FOUND"
  }
}
</pre>

'''Problematic Command'''
<pre>
curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash-exp-image:generateContent" \
  -H 'Content-Type: application/json' \
  -H 'X-goog-api-key: GEMINI_API_KEY' \
  -X POST \
  -d '{
    "contents": [

'''Affected Model:''' gemini-2.0-flash-exp-image-generation

'''Troubleshooting Steps:'''
<pre>
# Set your API key
API_KEY="YOUR_API_KEY_HERE"
 
echo "Retrieving available Gemini models..."
curl -s "https://generativelanguage.googleapis.com/v1beta/models" \
  -H "X-goog-api-key: $API_KEY" | jq -r '.models[] | select(.name | contains("gemini")) | {name: .name, supportedGenerationMethods: .supportedGenerationMethods}'

  "supportedGenerationMethods": [
    "generateContent",
    "countTokens",
    "bidiGenerateContent"
  ]
}
</pre>

Issue Identified: Incorrect model name used. The valid model name is "models/gemini-2.0-flash-exp-image-generation", not "models/gemini-2.0-flash-exp-image"

Fixed Command
<pre>
curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash-exp-image-generation:generateContent" \
  -H 'Content-Type: application/json' \
  -H 'X-goog-api-key: GEMINI_API_KEY' \

=== How to resolve: Gemini Text-to-Image: 16:9 Aspect Ratio Not Working, Always Generates 1:1 Images ===
'''Question:'''

Has anyone experienced issues with Gemini's text-to-image function where you specify 16:9 aspect ratio but keep getting 1:1 square images?

'''Problematic prompt''' for Models: 2.5 Pro & 2.5 Flash
<pre>
Generate a cute young turtle, 3D style
Image size 16:9
</pre>

<pre>
Generate a cute young turtle, 3D style
landscape orientation, wide format
</pre>

'''Answer:'''

A Google Product Expert acknowledged this issue in official forums, describing it as a "known limitation." However, no timeline has been provided for when the functionality might be restored.<ref>Gemini Nano Banana users report 1:1 aspect ratio lock on image generation https://piunikaweb.com/2025/09/11/gemini-image-generator-aspect-ratio-problems/</ref><ref>What happened to imagegen quality?? - Gemini Apps Community https://support.google.com/gemini/thread/372012804?hl=en&msgid=372013964</ref>

I've actually tested both Gemini 2.5 Pro and 2.5 Flash models, specifying image dimensions in the prompt (Image size: 16:9) or generating landscape orientation (landscape orientation, wide format), and both have the same problem. If you can make API calls, you might try using the API to call other models.

If you want an online solution that works, you can try Google Whisk directly: https://labs.google/fx/tools/whisk/
The interface allows you to directly set three aspect ratios: square 1:1, portrait 9:16, and landscape 16:9.
