mountebank application terminating

[Naveen J N]

Hosted mountebank application with nodejs16 in openshift.

I observe application is terminating with below error and container is getting restarted many times.

/usr/mountebank/src/models/http/httpRequest.js:43

type = index !== -1 ? contentType.substr(0, index).trim() : contentType.trim();

^

TypeError: contentType.trim is not a function

Could anybody please help to fix this issue? Thanks
