[msg] => 'You are not authorized to execute this request.'

Hello
I try use for Fixed saving
GET /sapi/v1/lending/union/purchaseRecord (HMAC SHA256)

But got
stdClass#1
(
[code] => -1002
[msg] => ‘You are not authorized to execute this request.’
)

I enabled all restrictions except ‘Enable Margin’ because it blocked, but still the same got error code: -1002
What could be the problem?
