I'm pretty new to Inkscape, and cannot find any online tutorials for the problem I've encountered:

> I traced the bitmap of a single color png image and, as far as I know, cleaned it up well, then made an even pattern tile that should be able to repeat seamlessly.

> I have already tested my pattern the only way I know how by exporting as a PNG, and the lines didn't go away.

> I have turned off the stroke around each tile and lined them up with the snap toggled both off and on.

> I've tried making really thin strokes so they disappear after exporting, but to no avail. 

> I also started the pattern from scratch.

> I need the pattern to be on a gradient background.

I am using Inkscape 1.1.2. Please help!

Please share an Inkscape svg file for evaluation.

Sorry about that -- here's one

Actually, it *is* stroke lines.

Note the stroke on the path 3064, the pattern basis.

I copied one rectangle from the original file and pasted into a new document, then used Pattern to Object.

Pattern with stroke removed.

Also some bad mojo in the original, making an invalid SVG.  I'd copy the good bits to a new document.

Awesome! That helps a lot, I didn't realize I could look under layers and objects. Thank you so much for the quick response

Thank you that explains issue I was having while playing with OP's file.
