Collection Variable is not being assigned

Question

If Env-Variable drawingmanage equals false the value gets assigned successfully(else block) whereas if it is true the value doesn't assign(if block)

if(pm.variables.get("drawingmanage") == 'true'){
            var stat=true;
            modelid.map((data)=>{
                data.models.map((modeldata)=>{
                    checkContainsdrawing(data.projectID,modeldata.modelID).then((datas)=>{
                        if(datas.json()._isSucceed && stat){
                            console.log(data)
                                pm.collectionVariables.set('projectid',data.projectID);
                                pm.collectionVariables.set('projectname',data.projectName);
                                pm.collectionVariables.set('modelid',data.models[0].modelID);
                                pm.collectionVariables.set('modelName',data.models[0].name);
                                stat=false;
                        }
                    }).catch((err)=>{
                        console.log('failed');

                })
            })
        })


}else{

    pm.test("Get Project ID and Project Name", function () {
        console.log('No drawing management selected');
        pm.collectionVariables.set('projectid',modelid[0].projectID);
        pm.collectionVariables.set('projectname',modelid[0].projectName);
    });

    pm.test("Get Model ID and Model Name", function () {
        pm.collectionVariables.set('modelid',modelid[0].models[0].modelID);
        pm.collectionVariables.set('modelName',modelid[0].models[0].name);
    });  
}

checkContainsdrawing Function

let checkContainsdrawing=(projectid,modelid)=>{
    const urldata=(projectid,modelid)=>{
    return {
        url:`${pm.variables.get("url")}api/blm/pdm/drawing?pid=${projectid}&mid=${modelid}`,

        method:'GET',
        header: {
            Authorization: pm.collectionVariables.get('authtoken')
        }
    }
    }
    return new Promise((resolve,reject)=>{
        pm.sendRequest(urldata(projectid,modelid),(err,res)=>{
            if(err){
                reject(err);
            }

            resolve(res);
        })    
    })

}

My test scenario

My main aim is to run the API automation without any testdata so i am using API parameritizing same pattern as the website works coming to explain this test scenario below

1. This API lists all the project where the user has access
2. Project may or may not contains model
3. So here i want to filter the projects which has model
4. And again to the model i want to validate whether the model contains a note sheet
5. For this i am making request to an API to check whether there is an note sheet to that particular project and model if there i am assigning to a collection variables which will be used in all Test

Problem

THe send requests work asynchronously and hence get resolved only at the end, so to avoid this, use set time out,

Whichever functions that use the specific collection variable, wrap it with set time out.

Fix:

if(pm.variables.get("drawingmanage") == 'true'){
            var stat=true;
            modelid.map((data)=>{
                data.models.map((modeldata)=>{
                    checkContainsdrawing(data.projectID,modeldata.modelID).then((datas)=>{
                        if(datas.json()._isSucceed && stat){
                            console.log(data)
                                pm.collectionVariables.set('projectid',data.projectID);
                                pm.collectionVariables.set('projectname',data.projectName);
                                pm.collectionVariables.set('modelid',data.models[0].modelID);
                                pm.collectionVariables.set('modelName',data.models[0].name);
                                stat=false;
                        }
                    }).catch((err)=>{
                        console.log('failed');

                })
            })
        })


}else{

    pm.test("Get Project ID and Project Name", function () {
        console.log('No drawing management selected');
        pm.collectionVariables.set('projectid',modelid[0].projectID);
        pm.collectionVariables.set('projectname',modelid[0].projectName);
    });

    pm.test("Get Model ID and Model Name", function () {
        pm.collectionVariables.set('modelid',modelid[0].models[0].modelID);
        pm.collectionVariables.set('modelName',modelid[0].models[0].name);
    });  
}

    setTimeout(function() {
     console.log("The collection varaible is")
    console.log(pm.collectionVariables.get('projectid'))

    }, 5000);

OR

 if (pm.variables.get("drawingmanage") == 'true') {
        var stat = true;
        modelid.map((data) => {
            data.models.map((modeldata) => {

                const urldata=(projectid,modelid)=>{
                    return {
                        url:`${pm.variables.get("url")}api/blm/pdm/drawing?pid=${projectid}&mid=${modelid}`,

                        method:'GET',
                        header: {
                            Authorization: pm.collectionVariables.get('authtoken')
                        }
                    }
                    }

                pm.sendRequest(urldata(data.projectID,modeldata.modelID), (err, datas) => {
                    if (datas.json()._isSucceed && stat) {
                        console.log(data)
                        pm.collectionVariables.set('projectid', data.projectID);
                        pm.collectionVariables.set('projectname', data.projectName);
                        pm.collectionVariables.set('modelid', data.models[0].modelID);
                        pm.collectionVariables.set('modelName', data.models[0].name);
                        stat = false;
                    }
                })
            })
        })


    } else {

        pm.test("Get Project ID and Project Name", function () {
            console.log('No drawing management selected');
            pm.collectionVariables.set('projectid', modelid[0].projectID);
            pm.collectionVariables.set('projectname', modelid[0].projectName);
        });

        pm.test("Get Model ID and Model Name", function () {
            pm.collectionVariables.set('modelid', modelid[0].models[0].modelID);
            pm.collectionVariables.set('modelName', modelid[0].models[0].name);
        });
    }

    setTimeout(function() {
     console.log("The collection varaible is")
    console.log(pm.collectionVariables.get('projectid'))

    }, 5000);

You can wrap all the remaining code like

setTimeout(function() {

       pm.test("Status code is 200", function () {
              pm.response.to.have.status(200);
        });

       pm.test("Status code is 200", function () {
          pm.response.to.have.status(200);
       });

}, 5000);

Here, the function is evoked automatically after 5 seconds by the time the callback time gets resolved.

Note: you need to do this only for the particular request because the next request is executed only after the timeout function is complete. SO all other requests will have the updated value.
