Store API Request returns invalid version or invalid vendor number

As the title states, I am having an issue requesting sales reports. Here are my parameters:

Code Block 
    'filter[frequency]'=>'DAILY',
    'filter[reportDate]'=>'2020-11-01',
    'filter[reportSubType]'=>'SUMMARY',
    'filter[reportType]'=>'SALES',
    'filter[vendorNumber]'=>XXXXXXXX,
//    'filter[version]'=>'1_0'

This request seems to meet the requirements set at the bottom of doc (https://developer.apple.com/documentation/appstoreconnectapi/download_sales_and_trends_reports)

But it still doesnt work for me. As it is above, it returns:

"status" : "400",
"code" : "PARAMETERERROR.INVALID",
"title" : "A parameter has an invalid value",
"detail" : "Invalid vendor number specified. Try again.",
"source" : {"parameter" : "filter[vendorNumber]"

If I uncomment the version, I get:

"status" : "400",
"code" : "PARAMETERERROR.INVALID",
"title" : "A parameter has an invalid value",
"detail" : "The version parameter you have specified is invalid. The latest version for this report is 1_0.",
"source" : {"parameter" : "filter[version]"

Obviously that is the same version I have in my parameters so I think something is wrong with this error or something has changed in the API and it isnt in the document linked above.

I quadruple checked the vendor number and it is right. I can use some ideas or some advice if someone has seen this issue and was able to resolve it.

Thanks in advance.
