Exception while making BigQuery call from java through tekton pipeline

Question

I am working on tekton pipeline that calls my java code which will make calls to the bigquery database and get the response into excel formatted file. By referencing google docs I have created tekton task and java code but I am getting java.io.IOException: Error reading credentials from stream, 'type' value 'external_account' not recognized. Expecting 'service_account'. error in java code. Below is my java code and tekton task

Tekton task :

        try {

          // once, and can be reused for multiple requests.
            BigQuery bigquery = BigQueryOptions.newBuilder().setProjectId(System.getProperty("GCP_PROJECT_ID"))
                    .setCredentials(
                            ServiceAccountCredentials.fromStream(new FileInputStream(System.getProperty("GOOGLE_APPLICATION_CREDENTIALS")))
                    ).build().getService();

          QueryJobConfiguration queryConfig = QueryJobConfiguration.newBuilder(query).build();

          TableResult results = bigquery.query(queryConfig);

          results
              .iterateAll()
              .forEach(row -> row.forEach(val -> System.out.printf("%s,", val.toString())));

          System.out.println("Query performed successfully.");
        } catch (Exception e) {
          System.out.println("Query not performed \n" + e.toString());
        }
      }

I have printed the logs, I am getting all the details that are passed from tekton pipeline.

Can someone help me to resolve this issue.
