Error thrown at line 513
this.promClientMetrics.api_response_size_bytes.labels(req.method,req.sws.api_path,res.statusCode).observe( req.sws.res_clength ? req.sws.res_clength : 0 );

if(req.sws.res_clength) = null. if response.c_length = 0;

Propagated from all the way from response intercept.

FIX
this.promClientMetrics.api_response_size_bytes.labels(req.method,req.sws.api_path,res.statusCode).observe( req.sws.res_clength ? req.sws.res_clength : 0 );

added a ternary operator to fix the issue.

Let me know if this is an actual bug, will submit a PR.

Actually, backtracked it to
swsCoreStats.js line 211

        resContentLength = res['_contentLength']; // doesn't check if it's null. Can add a check if res._contentLength is null, it will jump to taking the value from the header. 
    }else{
        // Try header
        if(res.hasHeader('content-length')) {
            resContentLength = res.getHeader('content-length');
        }
    }```

Changing the above code to the following worked for me:

    if ("_contentLength" in res && res['_contentLength'] !== null ){
        resContentLength = res['_contentLength'];
    }else{
        // Try header
        if(res.getHeader('content-length') !==null ) {
            resContentLength = parseInt(res.getHeader('content-length'));
        }
    }
