Error in Picrust 2 analysis

Hi everyone, I was trying to do picrust2 analysis for my data, I was using custom-tree-pipeline for my analysis. I had successfully constructed the SEPP tree… Then followed as given in the PiCRUST2 tutorial.

qiime picrust2 custom-tree-pipeline --i-table Pyro-dada2-denoise/pyro-LogMPIE-table.qza --i-tree Downloads/Galaxy24-[picrust-tree.qza].qza --p-threads 8 --output-dir PiCRUST2-pyro-LOgMPIE-results --p-max-nsti 2 --p-highly-verbose --verbose
