Adding file to GitHub using java client - org.eclipse.egit.github.core - github

Question

I am trying to add a file to a repository using the below code but I am getting below error. I just want to add a file for now.
org.eclipse.egit.github.core.client.RequestException: Invalid request.
For 'properties/email', nil is not a string. For 'properties/name',
nil is not a string. For 'properties/email', nil is not a string. For
'properties/name', nil is not a string. (422) at
org.eclipse.egit.github.core.client.GitHubClient.createException(GitHubClient.java:552)
at
org.eclipse.egit.github.core.client.GitHubClient.sendJson(GitHubClient.java:643)
at
org.eclipse.egit.github.core.client.GitHubClient.post(GitHubClient.java:757)
at
org.eclipse.egit.github.core.service.DataService.createCommit(DataService.java:397)
I sense that it is expecting some properties but how to supply this is not clear. What is that i am missing?

Answer 1

After some debugging, found that email and name values are coming as null which is the source of the issue.
Adding below two lines will solve the issue:
author.setName( userName );
author.setEmail(email);
