unknown command error while posting files to solr

Question

I am trying to post the following json format of the file to solr

{"userName": "Bill", "stars": 4, "review_id": "-TsVN230RCkLYKBeLsuz7A", "type": "review", "business_name": "Eric Goldberg, MD", "user_id": "zvJCcrpm2yOZrxKffwGQLA", "text": "Dr. Goldberg has been my doctor for years and I like him. I've found his office to be fairly efficient. Today I actually got to see the doctor a few minutes early! \n\nHe seems very engaged with his patients and his demeanor is friendly, yet authoritative. \n\nI'm glad to have Dr. Goldberg as my doctor."}

However I get the error

Response: {"responseHeader":{"status":400,"QTime":32}," error":{"msg":"Unknown command 'user_name' at [12]","code":400}}

while I am trying to do

post.sh -c coreName fileName.json

This is driving me crazy. I have unloaded the core and created it again to see if previous attempts to post files is causing this error. But that did not help.

Solr is looking for a command (like 'add') when you send an object, so you need to either add the command, as such:

{"add": {"doc":{"userName": "Bill", "stars": 4, "review_id": "-TsVN230RCkLYKBeLsuz7A", "type": "review", "business_name": "Eric Goldberg, MD", "user_id": "zvJCcrpm2yOZrxKffwGQLA", "text": "Dr. Goldberg has been my doctor for years and I like him.  I've found his office to be fairly efficient.  Today I actually got to see the doctor a few minutes early!  \n\nHe seems very engaged with his patients and his demeanor is friendly, yet authoritative.    \n\nI'm glad to have Dr. Goldberg as my doctor."}}}

Or place it in an array:

[{"userName": "Bill", "stars": 4, "review_id": "-TsVN230RCkLYKBeLsuz7A", "type": "review", "business_name": "Eric Goldberg, MD", "user_id": "zvJCcrpm2yOZrxKffwGQLA", "text": "Dr. Goldberg has been my doctor for years and I like him.  I've found his office to be fairly efficient.  Today I actually got to see the doctor a few minutes early!  \n\nHe seems very engaged with his patients and his demeanor is friendly, yet authoritative.    \n\nI'm glad to have Dr. Goldberg as my doctor."}]
