Image reader is not reader PNG files properly

[JaySmith123]

I have an issue with reading PNG files from a folder.

The below workflow reads PNG images fine. But when I add a particular Image (Image 1) to the folder which is also the same filetype, it fails.

Do you know what the issue could be?

Thanks in advance

Do you know what the issue could be?

Without details about the additional file I can only try to guess.
Is the file format (not the extension) really PNG?
What error(s) does the node tell you?
Did you try another PNG-file instead of the image#1?

Hi, yes the file format is PNG I think it says that in the screenshot above and I tried with another PNG file but it still did not work. This is the error I get.

Also this is the PNG file I am trying to read.

Hope this helps.

This is a similar workflow to the one I’m using. I just added the PNG of the house and it doesnt seem to read it.

the png file format could be the problem, may be i’m wrong.

i try to create the same conditions (adding other png files) to see if i can reproduce the issues.
below is to share my findings

1. added other files to the ‘simpsons collection’ in my local folder.
   
2. confirming the png type format.
   
3. it executed properly when read through knime nodes.
   

rgds
knime 5.1
linux mint 21.2
