JRXML upload from Jenkins give HTTP-500 but works elsewhere - jenkins

Question

I am using Jasper REST API to publish reports on Jasper Server.
Below are the scenarios:
When I upload the .JRXML file from POSTMAN and then create a report from POSTMAN using the JRXML. It works.
When I upload the .JRXML file from POSTMAN and then create a report from Jenkins using the JRXML. It works.
When I upload the .JRXML file from Jenkins and then create a report from Jenkins using the JRXML. It gives me HTTP 500 Error
When I upload the .JRXML file from Jenkins and then create a report from Jenkins using the JRXML. It gives me HTTP 500 Error.
I have even tried with cURL and it works fine. Its just the Jenkins where it gives the error. I have tried a lot of things but it has no outcome.
cURL from POSTMAN:
#To upload JRXML
curl --location --request POST 'https://server-url/jasperserver-pro/rest_v2/resources/Reports/' \
--header 'Content-Type: application/jrxml' \
--header 'Content-Disposition: attachment; filename=form.jrxml' \
--header 'Content-Description: Uploaded jrxml file POSTMAN' \
--header 'Authorization: Basic %Base64 Creds%' \
--data-binary 'report-templates/form.jrxml'
#To create report
curl --location --request POST 'https://server-url/jasperserver-pro/rest_v2/resources/Reports' \
--header 'Content-Type: application/repository.reportUnit+xml' \
--header 'Authorization: Basic Base64 Creds' \

What am I doing wrong? Any help is greatly appreciated.

Alright, so I got it working.
Apparently, I was unaware of the fact that when referencing/passing a file with --data-binary option, you need to prepend it with the '#' symbol.
Therefore changing line no.61 from --data-binary "$WORKSPACE/report-templates/${JRXML_FILE}" to --data-binary "#$WORKSPACE/report-templates/${JRXML_FILE}" did the trick. Otherwise, it was just saving the absolute path as the content of the file and not the actual XML data.
