Getting error while evaluating valuesets

const valueset = ctx.codeService.findValueSet(this.id, this.version) || new dt.ValueSet(this.id, this.version);

Please help me for the same.
Thanks

Hi @nehaghub. If I had to guess, it seems like you are not passing in a CodeService when you construct the cql-execution Executor. The CodeService instance is the 2nd argument in the Executor constructor. See the Overview.

If you aren't passing one in to the constructor, then you need to do so. If you're using value sets from VSAC, then you can use the cql-exec-vsac code service.

If you are passing in a code service and still getting this error, then we'll need more information:

• What version of cql-execution are you using?
• Based on the file paths, it looks like you are not using it as an npm dependency, but have cloned the repository and are running the code directly, is that right?
• Can you provide any example code of how you are building and or running the executor?

Hi,

1. I am using "version": "2.4.1".
2. Yes, I am using this way.
3. Below is my code
   const fs = require('fs');
   const path = require('path');

const cqlfhir = require('../lib');
const vsac = require('../../cql-exec-vsac');
const cql = require('../../cql-execution/lib/cql');

parameters = {
"Measurement Period" : new cql.Interval (
new cql.DateTime(1952,1,1,0,0,0,0),
new cql.DateTime(2021,1,1,0,0,0,0)
)
}

const elmFile = JSON.parse(fs.readFileSync('C:/Users/neha.f.goel/tt/bcs.json', 'utf8'));
const libraries = {
FHIRBase:JSON.parse(fs.readFileSync('C:/Users/neha.f.goel/tt/CCS_HEDIS_MY2022-1.1.0/CCS_HEDIS_MY2022-1.1.0/libraryElm/NCQA_FHIRBase-1.1.0.json', 'utf8')),
FHIRHelpers: JSON.parse(fs.readFileSync('C:/Users/neha.f.goel/tt/CCS_HEDIS_MY2022-1.1.0/CCS_HEDIS_MY2022-1.1.0/libraryElm/FHIRHelpers-4.0.1.json', 'utf8'))
};
)
const library = new cql.Library(elmFile, new cql.Repository(libraries));

const bundles = [];

const patientsPath = 'mcode1_0_longitudinal/longitudinal/female';
for (const fileName of fs.readdirSync(patientsPath)) {
const file = path.join(patientsPath, fileName);
if (!file.endsWith('.json')) {
continue;
}
const json = JSON.parse(fs.readFileSync(file));
bundles.push(json);
}

const patientSource = cqlfhir.PatientSource.FHIRv401(); // or .FHIRv300() or .FHIRv400()

patientSource.loadBundles(bundles);

// let valueSets = [];

// if (elmFile.library && elmFile.library.valueSets && elmFile.library.valueSets.def) {
// valueSets = elmFile.library.valueSets.def;
// }

// const codeService = new vsac.CodeService('C:/Users/neha.f.goel/tt/jim_cql/valuesets/vsac_cache/', true);

console.log("b4 execution") ;
const executor = new cql.Executor(library);

// const executor = new cql.Executor(library, codeService,parameters);
const results = executor.exec(patientSource);

console.log(JSON.stringify(results, undefined, 2));

I apologize for the long delay in getting back to you. In your code above, you have commented out the lines that initialize a code service and pass it into the Executor. As I noted in my previous response, you need to pass in a CodeService as the 2nd argument to the executor.
