If the content type doesn't have either of 'text', 'text_long', 'text_with_summary' field, the node view page throws an error. Moreover readtime may not be desirable for each content type.
Add a checkbox on content type edit form to configure readtime per content type
New checkbox under Read time tab on content type edit form.
By default readtime will be disabled.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Thank you all for the support.
I merged it with the 2.x branch and it will be available in the next release.
