Solidity Overflow in my web3 code but works in oneclickdapp

Question

This is the link of oneclickapp which is working https://oneclickdapp.com/center-east/.

This is Link of Contract:https://rinkeby.etherscan.io/address/0x33febb8f192941a87d87ef70cc5f4427c44bf29e#code

Contract Source Code:

My own ReactJs code:

        try{
            await this.DMR.methods.getPatientDetails(this.state.account).call().then((res)=>{
                let result = res;
                console.log(result);
            });
        }
        catch(e){
            await this.setState({load:false});
            console.log(e);
        }

Instructions to test functionality:

• First You need to create Patient using addPatient function,You can use above oneclickapp link to create patient.

• Then use getPatientDetails function to get patient info(should be your own address through which you created patient),You can view your details in oneclick app.

Using the oneclickapp works fine,but my own web3 source code:

Gives me Error:

Error: overflow (fault="overflow", operation="toNumber", value="3963877391197344453575983046348115674221700746820753546331534351508065746944", code=NUMERIC_FAULT, version=bignumber/5.0.7)

I don't understand why overflow occurs as the function returns all string.

Note: DMR is my contract instance which is working fine as I am able to get other functions correctly.

Answer 1

You shouldn't mix promise constructs together (async/await vs .then), as to the direct issue do you mind dumping the full stack trace?

try{
    const res = await this.DMR.methods.getPatientDetails(this.state.account).call();
    console.log(res);
}
catch(e){
    await this.setState({load:false});
    console.log(e);
}
