Cell ranger multi for demultiplexing FB files and GEX files

Question

[Shloka]

I have my feature csv file which is multiplexing capture, i have feature barcode fastq files, gex fastq files and i was trying to run cell-ranger multi but this error shows up (error] Deplex Error: No valid tags were identified during the initialization phase.

This can indicate corrupt or problematic data.) i do not know how to troubleshoot

Demultiplexing is typically done using Illumina software? Have you done this already?: https://www.10xgenomics.com/support/software/cell-ranger/analysis/inputs/cr-direct-demultiplexing
