.build.info file for 8.3.7

I am trying to extract vmaps files from the 8.3.7 client, but launching "extract all" in extractor.bat immediately give me this error :

I found online that it was because my client missed the .build.info file, but I can't find one anywhere. Does someone know where I can find one ?

(I am using the last 837 release on the github)
