An error occurred when attempting to search Windows Update

I use SSM document AWS-RunPatchBaseline to patch my windows servers. while trying to run it, I had this error with one of my servers:

I tried to check this key : HKEY_LOCAL_MACHINE > Software > Policies > Microsoft > Windows > WindowsUpdate > UseWUServer but I could not find it inside my server. My server is windows server 2012 R2. I also looked into the CPUUtilization metric on Cloudwatch during the execution of the patch baseline and it seemed normal. Any clues?
