rapidjson internal assertion failure: IsObject()

[AndreaGhiroldi]

I've installed Salmon and made the index, but once I run the analysis, I've got this error:

(salmon) andrea@Precision-7920-Tower:/hdd_a/andrea/Salmon$ sudo salmon quant -i GRCh38_salmon_index/ -l A -r /hdd_a/andrea/Salmon/Fastq/1_vehicle_R1.fastq.gz --validateMappings -o /Output/

salmon (mapping-based) v0.12.0

[ program ] => salmon

[ command ] => quant

[ index ] => { GRCh38_salmon_index/ }

[ libType ] => { A }

[ unmatedReads ] => { /hdd_a/andrea/Salmon/Fastq/1_vehicle_R1.fastq.gz }

[ validateMappings ] => { }

[ output ] => { /Output/ }
