File declaration throwing error in JMeter, JSR223 sampler with groovy script

Question

I am using the following script to handle a file upload request for my application. I am using this script inside a JSR223 Sampler and the code block

import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.HttpClientBuilder;


def imageFileName = "C:\\Users\\IMAGES\\IMG00001.dcm"

def urlRequest='https://<app-server>/api/v3/storage/namespace/7c762733-009f-4527-81ea-571d1cf6e9d2/image?sid=${SIDVALUE}&study_uid=1.2.300.0.7230010.3.1.2.2595064201.8112.1216202112026121&image_uid=1.2.840.113704.7.1.0.1356918323635126.1521373008.110'


def postRequest = new HttpPost(urlRequest);
def file = new File(imageFileName);
def builder = MultipartEntityBuilder.create();

builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
builder.addBinaryBody("file", file, ContentType.DEFAULT_BINARY, imageFileName);
def entity = builder.build();
post.setEntity(entity);
def response = HttpClientBuilder.create().build().execute(postRequestt);

ERROR I am getting: When I am removing the file declaration code execute with error.

I tried with C:\Users\IMAGES\IMG00001.dcm instead of C:\\Users\\IMAGES\\IMG00001.dcm, but no luck

Your post is not declared anywhere
Your postRequestt is not declared anywhere
You shouldn't refer JMeter Functions or Variables as ${SIDVALUE}, use vars shorthand for JMeterVariables instance instead

Fixed code would be something like:

import org.apache.http.client.methods.HttpPost
import org.apache.http.entity.ContentType
import org.apache.http.entity.mime.HttpMultipartMode
import org.apache.http.entity.mime.MultipartEntityBuilder
import org.apache.http.impl.client.HttpClientBuilder

def imageFileName = "C:\\Users\\IMAGES\\IMG00001.dcm"

def urlRequest = 'https://<app-server>/api/v3/storage/namespace/7c762733-009f-4527-81ea-571d1cf6e9d2/image?sid=' + vars.get('SIDVALUE') + '&study_uid=1.2.300.0.7230010.3.1.2.2595064201.8112.1216202112026121&image_uid=1.2.840.113704.7.1.0.1356918323635126.1521373008.110'


def postRequest = new HttpPost(urlRequest);
def file = new File(imageFileName);
def builder = MultipartEntityBuilder.create();

builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
builder.addBinaryBody("file", file, ContentType.DEFAULT_BINARY, imageFileName);
def entity = builder.build();
postRequest.setEntity(entity);
def response = HttpClientBuilder.create().build().execute(postRequest);
