Team Foundation Server 2018 Data is Null

Hi All,

I am trying to configure Team Foundation Server 2018 with SQL server but i am getting an error at readiness check validation

 

" TF255407: An error occurred while attempting to validate the configuration database. Error message: Data is Null. This method or property cannot be called on Null values."

 

I already have TFS setup running on one of the server which is currently live and its working fine. I want to setup one more server to test the backup of TFS data, so for that i have installed same version of TFS i.e. 2018 and SQL server 2016. Below are all the activities which i have performed.

 

  • Running TFS Instance Details.
  1. TFS Version: 2018
  2. SQL Server: 2016 SP1
  3. OS: Windows server 2019
  4. TFS DB's:
    • Tfs_Configuration: 1.5 GB
    • Tfs_Projects: 48 GB
    • Tfs_Products: 24 GB
    • Tfs_AppDevelopment: 29 GB
    • Tfs_Migration: 7 GB
  • New Server Details.
  1. TFS Version: 2018
  2. SQL Server: 2016 SP1
  3. OS: Windows server 2016

All above db backups i have restored on new server. Installed TFS 2018 and when trying to configure i am selecting existing deployment.

 

Regards

Imran Shaikh
