client.js:2 ContractFunctionExecutionError: The contract function "totalSupply" returned no data ("0x")

[engbz]

Greetings to everyone. I'm getting the total number of minted nfts of a collection. When I connect to the wallet, it shows the instantly printed coins without any problems. When I disconnect the wallet, I get the following error. And the minted tokens are not visible.

`client.js:2 ContractFunctionExecutionError: The contract function "totalSupply" returned no data ("0x").

This could be due to any of the following:

• The contract does not have the function "totalSupply",
• The parameters passed to the contract function may be invalid, or
• The address is not a contract.

Contract Call:
address: 0xFC02a4589DE78dB617025c7cC7B352a6e7A7930E
function: totalSupply()
