Problem: “The item has no binary field 'image' [item 0]” when using Google Gemini → Edit Image

Describe the problem/error/question

I’m trying to use the Google Gemini (PaLM) API → Edit Image node to edit or blend two images based on a text prompt.
Both input images are passed through a Merge node — the goal is to have one as a base (file1.jpg) and the other as a context/background (file2.jpg).

However, the Gemini node doesn’t recognize the second binary image and throws a “no binary field” error.

What is the error message (if any)?

The item has no binary field 'image' [item 0]
Check that the parameter where you specified the input binary field name is correct, and that it matches a field in the binary input.

Please share your workflow

Share the output returned by the last node

Edit: This was my first try. Using the filed name.

It won’t work because there are two issues:

The Merge node outputs two items, so Gemini is executed twice, once for each image.
Solution: Set the Merge node to Combine Mode and use All Possible Combinations so that it outputs a single item containing all images.
The Binary Field Name you’re using has the wrong expression.
Easy fix: Use fixed mode and simply specify the correct binary name.

So it should look like this:

@mohamed3nan I have run into a similar issue. I assume its a similar answer.

This is my first time posting in the community so forgive me if this is not the right way to do it. I am happy to pay.

Mine appears to be with one of the runs that comes through.

I was not also sure if its to do what is coming into it.
