My version is 0.26.0

What are the steps to reproduce?

1. Take an image and resize it to 1x1
2. Try to get stats from it

What is the expected behaviour?

To get stats

Are you able to provide a minimal, standalone code sample, without other dependencies, that demonstrates this problem?

This is the part from my code:

mainPipeline
.clone()
.extract({ top: 0, left: 0, width: widthPixel, height: heightPixel })
.resize(1, 1)
.toBuffer()
.then(buffer => sharp(buffer).stats());

It works fine if I do resize with 2, 2 or 1, 2 or if I remove the resize completely but it doesn't work with 1, 1, it's not the problem with resize though because I was able to output that 1x1 to a file and that worked, only reading stats doesn't work.
I'm doing the resizing because I want to get the average colour of the image and it works better if I resize the image to 1x1 and then read the colours of that pixel than if I read the mean values of each channel.
This is the error in the console:

What is the output of running npx envinfo --binaries --system?
