insertRowsAsStream not showing full error log

[luna-ci]

I have tried created a table using the api successfully with 2 fields as nullable.
However I was unable to insertRowsAsStream as using code below

const params = {
        datasetId: "Event",
        tableId: "navigation9",
        projectId: "xxxx-9a8cd",
        rows: [
          { Name: "test0", Age: 0 },
          { Name: "test2", Age: 1 },
          { Name: "test3", Age: 2 },
          { Name: "test4", Age: 3 },
          { Name: "test5", Age: 0 }
        ]
      }

insertRowsAsStream(params)

const insertRowsAsStream = ({ datasetId, tableId, rows, projectId }) => new Promise((resolve, reject) => {
  const BigQuery = require('@google-cloud/bigquery');

  // Instantiates a client
  const bigquery = BigQuery({
    projectId: projectId
  });

  console.log('insertRowAsStream rows = ', JSON.stringify(rows, null, 2))

  // Inserts data into a table
  bigquery
    .dataset(datasetId)
    .table(tableId)
    .insert(rows)
    .then((insertErrors) => {
      console.log('Inserted:');
      rows.forEach((row) => console.log(row));

      if (insertErrors && insertErrors.length > 0) {
        console.log('Insert errors:');

        insertErrors.forEach((err) => console.error(err));
        reject('ERROR: ' + JSON.stringify(insertErrors, null, 2));
      } else {
        resolve('Sucessfully Inserted')
      }
    })
    .catch((err) => {

      console.error('ERROR:', err);
      reject('ERROR:' + err);

    });
  // [END bigquery_insert_stream]
});

The log result i got is not very helpful

Inserted: 
{ Name: 'test0', Age: 0 }
{ Name: 'test2', Age: 1 }
{ Name: 'test3', Age: 2 }
{ Name: 'test4', Age: 3 }
{ Name: 'test5', Age: 0 }
Insert errors:
{ kind: 'bigquery#tableDataInsertAllResponse' }

Here is do not know what causing the error

I've the same issue when run this code in Cloud Function. No errors are returned but no rows are in Bigquery
