A function whose declared type is neither 'void' nor 'any' must return a value.

// You probably do it like that
import { JSHash, CONSTANTS } from "react-native-hash";

async function hashSha1(param1: string): Promise<string> {
    await JSHash(`${param1}`, CONSTANTS.HashAlgorithms.sha1)
    .then(hash => {
        return hash  // Promise returned this case
    })
    .catch(e => console.log(e));  // You do not return this case so promise give error
}

// Then avoid of error all ways needs to be return
import { JSHash, CONSTANTS } from "react-native-hash";

async function hashSha1(param1: string): Promise<string> {
    const hash = await JSHash(`${param1}`, CONSTANTS.HashAlgorithms.sha1)
    return hash  // Promise returned
}  // So all promises returned
