ScriptError: Error: Exception: Limit Exceeded: URLFetch URL length

Hey, I am using bulk product sync with the pro version. I am updating the price and stock quantities in the SKU section of the sheet. It works fine with 700 products, but it shows the following error when product limits are exceeded.

ScriptError: Error: Exception: Limit Exceeded: URLFetch URL length

I have around 50000 plus products and want to update the price and stock quantity. I am facing this issue, so please let me know how to fix this.

Regards!
