ElasticSearch Error : Failed to update template: Request failed with status code 400

[nagarobo]

Issue Description

I am using swagger-stats with Elasticsearch 8.6.0 (official Docker image), configured as follows:
• Elasticsearch version: 8.6.0
• swagger-stats version: 0.99.7
• Elasticsearch running with security enabled (xpack.security.enabled=true)
• Basic authentication enabled with elastic user and password

When swagger-stats tries to update the index template in Elasticsearch, I get the following error:

sws:elastic Failed to update template: Request failed with status code 400 +0ms

My configuration

const app = express();
const port = 3000;
const swaggerSpec = require('./petstore.json');
app.use(swStats.getMiddleware({
  name: 'swagger-stats-testapp',
  version: '0.99.7',
  timelineBucketDuration: 60000,
  uriPath: '/swagger-stats',
  swaggerSpec: swaggerSpec,
  elasticsearch: 'http://localhost:9200',
  elasticsearchUsername:"elastic",
  elasticsearchPassword:"admin123"
}));
