Call a REST API using incron and bash script?

Question

I'm using incron to check if XML files are uploaded in a folder Depot using :

/home/parallels/Desktop/Depot IN_CLOSE_WRITE /home/parallels/Desktop/Depot/add.sh $#

When a new file is detected, the following bash script add.sh (which is in the Depot folder) is called :

#!/bin/bash
fileContent="$(cat $1)"

curl \
--header "Content-type: application/json" \
--request POST \
--data '{
    "user": "user@mail.com",
    "fileName": "'"$1"'",
    "content": "'"$fileContent"'"
}' \
http://url/of/the/api

The $1 var contains the name of the file, and the $fileContent var contains the XML content of the file.

The thing is, when I manually call the bash script from the command line (when there's already a XML file in the Depot folder) using :

./add.sh test.xml

everything works fine. But when I try to trigger the script by dropping a new XML file into the folder, it doesn't do anything, despite showing-up in the log, tail /var/log/syslog command giving the following result :

(parallels) CMD (/home/parallels/Desktop/Depot/add.sh test.xml)

The only way I could get it working (by dropping a file in the folder) is when the content var is already set in the script, like so :

#!/bin/bash
fileContent="$(cat $1)" <=== Not used anymore in this case

curl \
--header "Content-type: application/json" \
--request POST \
--data '{
    "user": "user@mail.com",
    "fileName": "'"$1"'",
    "content": "
        <node>
            <subnode>
                content
            </subnode>
        </node>
"
}' \

Am I missing something here ? Should I use another method than cat to retrieve the XML content ?

I managed to make it work !

I changed the incron command to :

/home/parallels/Desktop/Depot IN_CLOSE_WRITE /home/parallels/Desktop/Depot/add.sh #@/$#

and the bash script to :

#!/bin/bash
fileContent=`cat $1`
fileName=$(basename $1)

curl \
--header "Content-type: application/json" \
--request POST \
--data '
    {
        "user": "user@mail.com",
        "filename": "'"$fileName"'",
        "content": "'"$fileContent"'"
    }' \
http://url/of/the/api

I needed to send the full path of the file to the bash script (using $@/$#) for the cat function to work properly.
