For a contract view that accepts a list of managed buffers I was able to query from erdjs the view like this: let abi = new SmartContractAbi(abiRegistry, [`MyContract`]); let contract = new SmartContract({ address: address, abi: abi, }); let interaction: Interaction = contract.methods.getTournamentInfoList([ BytesValue.fromUTF8("tournament-01"), BytesValue.fromUTF8("tournament-02") ]); let queryResponse = await contract.runQuery( provider, interaction.buildQuery() ); Now I have an view that accepts only a wallet address and I'm trying to call the view like this let abi = new SmartContractAbi(abiRegistry, [`XLauncherStaking`]); let contract = new SmartContract({ address: address, abi: abi, }); let interaction = contract.methods.getClientReport( [BytesValue.fromUTF8("erd1mhhnd3ux2duwc9824dhelherdj3gvzn04erdw29l8cyr5z8fpa7quda68z")] ); let queryResponse = await contract.runQuery( provider, interaction.buildQuery() ); But I get empty response . If I call from erdpy it works getClientReport() { # erdpy wallet bech32 --decode erd1mhhnd3ux2duwc9824dhelherdj3gvzn04erdw29l8cyr5z8fpa7quda68z erdpy --verbose contract query ${ADDRESS} --function="getClientReport" \ --arguments 0xddef36c7865378ec14eaab6f9fdf236ca2860a6fae46d728bf3e083a08e90f7c \ --proxy=${PROXY} } How do I pass an wallet address using javascript SmartContract class?
