You need to switch the model you are using to fix this to another gemini model. Try one that does not say preview.

Let me know if this works!

I

m running imagen 4.0 ultra in the generate image node and in the edit image node you can’t choose a model

[achamm]

try readding the node, this is how it looks for me. Also ensure your n8n instance is updated all the way

[Soporte_USoft]

Hi! What version of n8n are you using?
Is it self-hosted or cloud?
I’m asking because I can’t change the model in the Gemini image edit node either

[achamm]

im on cloud and im able to change it, version 2.3.5

[achamm]

@Jon2 Can you update your n8n version to 2.0? This is likely the cause of your issue since your on version 1.

If you don’t know how, you can check out how to here

[achamm]

@Soporte_USoft Update your version most likely then.

I updated the n8n version today. The update worked and was downloaded. However, after the update, I can no longer access n8n. When I click on “Manage app,” either a tab opens with “n8n is starting up. Please wait” or a file is downloaded that cannot be opened.
