Error reading from the FASTA/Q stream. Minimum return code for left and right read was (-2).

Dear developer
Error reading from the FASTA/Q stream. Minimum return code for left and right read was (-2).
code salmon quant -i $IndexDir -p 15 -l A -1 ${CleanDataDir}/${treat}${CleanReads1Suffix} -2 ${CleanDataDir}/${treat}${CleanReads2Suffix} -o ${outDir}/${treat}

How should I go about solving this error or investigating its cause?

Best wishes!
