Error running sls deploy

Getting the error message below when I run sls deploy. The same command ran successfully last week and no code changes were made. Any help would be much appreciated.

Error: Error: Could not set up basepath mapping. Try running sls create_domain first.
Error: Error: ‘’ could not be found in API Gateway.
ConfigError: Missing region in config
at getDomain.then.then.catch (D:\Projects\abc-services\abc-service-admin\node_modules\serverless-domain-manager\index.js:175:15)

changed “serverless-domain-manager”: “^3.3.1” in the package.json and it solved the issue
