I simply need to run Trimmomatic, but he doesn`t see input files. May be you know how to deal with it?

#creating variables 
INPUT_DIR="path/folderinput"
OUTPUT_DIR="path/folderoutput"

APPENDIX=".fastq.gz"
APPENDIX1="_R1.fastq.gz"
APPENDIX2="_R2.fastq.gz"

TRIMMOMATIC="java -jar /home/path/trimmomatic-0.36.jar"

#creating a loop
for i in $INPUT_DIR/*$APPENDIX1
do
FORWARD=$(basename "$i")
REVERSE=${FORWARD/_R1.fastq.gz/$APPENDIX2}
FORWARDO=$OUTPUT_DIR/$FORWARD
REVERSEO=$OUTPUT_DIR/$REVERSE
FORWARDI=$i
REVERSE=${FORWARDI/_R1.fastq.gz/$APPENDIX2}

echo "Now I am processing PE reads $FORWARD and $REVERSE - Trimming"

$TRIMMOMATIC PE -phred33 -trimlog $FORWARDO_trim.log $FORWARDI $REVERSE ${FORWARDO%$APPENDIX}_trim.fastq.gz ${FORWARDO%$APPENDIX}_unpaired.fastq.gz ${REVERSEO%$APPENDIX}_trim.fastq.gz ${REVERSEO%$APPENDIX}_unpaired.fastq.gz ILLUMINACLIP:NexteraPE-PE.fa:2:30:10 MINLEN:75

echo "Done processing PE reads $FORWARD and $REVERSE - Trimming"

done

#And the error pops up
