imposter-3.22.0.jar - REST request with content-type=multipart/form-data - how to access the parts ? Groovy script returns null body

[rcoulonv]

I am using Java jdk-11.0.22 to run imposter-3.22.0.jar --plugin rest

How is it possible to retrieve using a Groovy script the parts of a REST request whose content-type=multipart/form-data ?
The Groovy script returns a null body while the content-length=48199 - see below:

Groovy script extract:
logger.info "DEBUG - context.request = " + context.request
logger.info "DEBUG - context.request.body = " + context.request.body
logger.info "DEBUG - context.request.formParams = " + context.request.formParams

Log console extract at execution
10:51:26 INFO s.r.a.s.c.v1 - DEBUG - context.request = Request{path='/myapi', method='POST', uri='http://127.0.0.1:8080/myapi', pathParams={}, queryParams={}, headers={mime-version=1.0, content-length=48199, host=127.0.0.1:8080, content-type=multipart/form-data; boundary="----=_Part_86_1037032677.1716281485976", connection=Keep-Alive, accept-encoding=gzip,deflate,br, user-agent=Apache-HttpClient/4.5.14 (Java/17.0.10)}, body=}
10:51:26 INFO s.r.a.s.c.v1 - DEBUG - context.request.body = null
10:51:26 INFO s.r.a.s.c.v1 - DEBUG - context.request.formParams = [:]

Thanks for your support

Hi @rcoulonv, thanks for raising this.

Here's an example using Imposter 3.40:

Testing the mock:

curl -F "text=hello" -F "[email protected]" localhost:8080

The script prints the following in the log:
