Kling 3.0 doesn't work in firefly

I’m trying to generate videos in Firefly using the Kling 3.0 model, but it keeps failing even though my prompts do not include any violent, sexual, or inappropriate content.

The prompts are very simple — usually just describing the character, the action, and the camera shot — but I repeatedly get the following error message:

“Can’t load. We can’t display the generated video. You can edit and try again.”

When I use other models, such as Veo 3 Fast, the same kind of prompts generate without any issue. However, with Kling 3.0, the generation fails whether I write a very short prompt or a longer, more detailed one.

Sometimes, the video does generate successfully with a certain prompt, but I have not been able to figure out why that specific prompt works while others fail. I have spent several days trying different prompt styles, but the results feel inconsistent and unpredictable.

Is Kling 3.0 supposed to have very strict prompt limitations inside Firefly, or could this be a server-side or model-related error?

This issue makes it very difficult to use Kling 3.0 reliably within Firefly, even for normal, safe video generation prompts.

I would appreciate it if you could look into this issue.

System Details: Specify your Operating System (OS) and Browser (including version numbers).
Workflow Context:
• Which Firefly function were you using? (e.g., Text to Image, Generative Fill, Text to Video, etc.)
• Which model was selected? (e.g., Firefly Image 3, Image 4 Ultra, Imagen 3).
• The full prompt you were using.
• Copies of any reference images, keyframes, or original images used.

Note: Here’s a useful article explaining the most common reasons that trigger the error you’ve been seeing

I’m using Generate Video with Kling 3.0 from a single still image. The image is a normal photograph and prompts are simple (e.g. “The man nods while listening. The other man gestures. Locked camera.”). The generation repeatedly fails or is rejected, even with extremely basic prompts. The same image and prompts work in other video-generation models, (VEO 3.1) and with Kling on another site, suggesting the issue is specific to the Firefly/Kling integration rather than the content. I’ve reduced the prompts to the simplest possible form and still cannot generate a result. Please investigate whether there is an issue with the Kling 3.0 implementation or moderation pipeline.

I am having the same issue. Kling 3.0 constantly returns “can’t load” error message. it does not matter what the prompt or image is. is this a known issue?
