Issue with ShowText Node Displaying Text in Single Line After Connecting to Custom OCR Node in ComfyUI

[AhmedAlkhateb2010]

I have developed a custom OCR (Optical Character Recognition) system where the workflow involves connecting the "Load Image" node to the OCR node and then to the "ShowText" node in ComfyUI. The setup works as expected, and the OCR node successfully extracts text from the input image. However, when the text is displayed in the "ShowText" node, each character appears on a new line. For example, if the OCR output is:

Hello World!

The "ShowText" node displays it as:

H
e
l
l
o

W
o
r
l
d
!

I verified the OCR node's output by logging the results in VSCode, and the text appears correctly formatted as a single string. However, in ComfyUI, the text is incorrectly rendered with each letter on a separate line.

This issue might be related to how the "ShowText" node is handling or interpreting the input from the OCR node. I suspect it could be related to formatting, line breaks, or unintended processing during node communication.

Could someone help identify the root cause or provide guidance on how to resolve this issue?

I'm not a developer, so I can't help you find the real cause. But is it possible that your node outputs a list of strings instead of a single string? Usually when the “Show Text” displays text this way, it means that it is given a list.

Maybe you can test with String List to String or similar node to see if the text will display correctly

You need to return string as a tuple data.
I.e.
That should be

return (strdata,)

Instead of

return strdata
