Fail normality test but the qqplot is a straight line [duplicate]

This question already has an answer here:

I am using SAS 9.4 . My aim is to find out whether my residual is normal or not, so i type this:

proc univariate data= residual normal; var rstd; qqplot rstd/ norml(mu=est sigma=est); run; 

In my output the qqplot is clearly a straight while 4 pavlue of statistic for the normality is less then 5%.

How can i interpret this?
