Why my baked object alway have the black line at seam?

hi guys, i have a problem that when i baked the low poly from high poly, the object alway have a black line at the seam i marked as a picture below , can anyone explain for me the problem and tip to remove this line , thank you!
here is my low poly mesh ( that have a black line at seam)

The most common mistake users make when using normal maps is that they don’t change their color space. By default it’s sRGB and for a normal map to work properly it should be Non-Color.

This can be changed in your shader editor in the node with your normal map texture.

Thank you, i’ll try it:)

i solved this, thank you very much!
