gocd: "Modification check failed for material" during 'git config remote.origin.url'

Hello,

I’m having a material check failure and Go isn’t giving any clear reason for it.

On the Go interface we have the following:

Modification check failed for material: URL: git@bitbucket.org:teamname/repository.git, Branch: topic [Jan-27 16:52:03]
Error performing command: --- Command --- git config remote.origin.url --- Environment --- {} --- INPUT ---- --OUTPUT --- --- ERROR --- ---

And on the log files:

2016-01-27 16:36:33,858  WARN [89@MessageListener for MaterialUpdateListener] MaterialDatabaseUpdater:121 - [Material Update] Modification check failed for material: URL: git@bitbucket.org:teamname/repository.git, Branch: topic
java.lang.RuntimeException: Error performing command: --- Command ---
git config remote.origin.url
--- Environment ---

--OUTPUT ---

--- ERROR ---
