how to process nanopore metagenome reads with QIIME 2?

I am also trying nanopore reads for Metagenome analysis using qiime2 I can able to import the data to artifact file but facing issue with while denoising with dada2 getting error as my reads contains above 1.4k reads

Plugin error from dada2:

No reads passed the filter. trunc_len (1400) may be longer than read lengths, or other arguments (such as max_ee or trunc_q) may be preventing reads from passing the filter.

Debug info has been saved to /tmp/qiime2-q2cli-err-2bgz5d7d.log

my commands are
qiime dada2 denoise-single
–i-demultiplexed-seqs single-end-demux.qza
–p-trim-left 0
–p-trunc-len 1400
–o-representative-sequences rep
–o-table table --o-denoising-stats stats
