Svn: E175002: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svn/BUR/!svn/vcc/default)

Hi All,
I am trying to migrate SVN to Gitlab with SVN history. So I used subgit, when I was trying to install subgit using git bash(subgit install project.git).I got failed and received the below error. Please advise me on this.
