issue with /sapi/v1/staking/personalLeftQuota

Hi,

I am facing problem only with using (GET “/sapi/v1/staking/personalLeftQuota”) i give the parameters for product and productId.

parameters = {
    "product": "STAKING",
    "productId": "Axs*90"
}

and i am getting the following error {“code”:-1022,“msg”:“Signature for this request is not valid.”}’

Note: when changing the productId to BTC001 i get the following error
{“code”:-9000,“msg”:“Project not exist with projectId BTC001”}

I am pretty sure that the signature is implemented correct. i have no issue when using any other API even the api for staking only this api has issue

code:-2008 invalid Api-Key ID,did you fix it?

This is most likely an encoding issue.

Could you try sign the endpoint with the following signature and provide the resulting query-string?

Signature: testsignature
