nginx: [warn] could not build optimal variables_hash, you should increase either variables_hash_max_size: 1024 or variables_hash_bucket_size: 64; ignoring variables_hash_bucket_size

Hi guys, when I include your default.conf, nginx -t tells me:

nginx: [warn] could not build optimal variables_hash, you should increase either variables_hash_max_size: 1024 or variables_hash_bucket_size: 64; ignoring variables_hash_bucket_size

this is my nginx.conf
