Qval not displayed

I am using the following code to run ccrepe on my microbiome data. My sample size is 6. Im not getting qval in my output. The qval column says NA for all corelations. I tried lowering the iterations too.
Any input on this?

ccrepe(
x = gbm.i.w.k.relab,
sim.score = cor, # default is spearman corelation
sim.score.args = list(method=“spearman”,use=“complete.obs”),
min.subj = 0,
iterations = 100,
concurrent.output = “crepe_gbm_taxa_i_w_k.csv”)
