Error while adding a new remote repository in JFrog's Artifactory

Question

I have requested for a trial version of JFrog Artifactory and trying to a new remote repository via the admin UI.

For example, I am adding the https://jcenter.bintray.com/ but I am getting an error saying "Error parsing json body" in UI.

2019-05-28 15:03:28,714 [http-nio-8081-exec-10] [ERROR] (o.a.r.c.e.JsonMappingExceptionMapper:23) - Error parsing json body

Please let me know what I am doing wrong here and is authentication required inorder to connect to any remote repo?

Answer 1

In the field Max Unique Snapshot (righthand side of the screenshot you pasted), you've entered an incorrect value. Right now it shows the value admin and it should be either an integer or a blank value.

To answer your second question, authentication isn't required to set up JCenter as a remote repository.
