Hi @Siddhant Pandey!

I see the error 'Connection refused' for localhost:27017.

• Are you starting a service at localhost:27017 and is it available when you try to connect to it?
• Can you try using 127.0.0.1 instead of localhost?

In case you are using MongoDB, you can make use of the services feature in pipelines.

You can read more about database and services containers in Pipelines here:

• https://support.atlassian.com/bitbucket-cloud/docs/databases-and-service-containers/

More details about MongoDB specifically can be found here:

Kind regards,
