Can't determine issue with JS storeClient function and error thrown

I have created two async functions within my JavaScript Zapier step to parse a raw webhook. The two async functions center around storeClient to "get" and "set" values on Storage by Zapier. However, I get an error thrown. I have a screen shot from Zapier test sub-step. Due to the way Zapier returns on error, I can't see any of my console.log output.

What have I done wrong with the async functions?

    <!-- language: lang-js -->
    // function to talk to Storage By Zapier to get a key
    //
    async function getStore(passKey) {
        try {
            const store = StoreClient(inputData.secret);
            const data = await store.get(passKey);
            console.log(`Here is the data from store: ${data}`);
            return data;
         } catch(error) {
            console.log(`We hit an error: ${error}`);
         }
     }

     // function to talk to Storage By Zapier to set a key and values
     //
     async function setStore(passKey, passTags) {
         try {
             const store = StoreClient(inputData.secret);
             await store.setMany({'email': passKey, 'tags': passTags});
         } catch(error) {
             console.log(`We hit an error: ${error}`);
         }
     }

     // for testing in editor
     //
     //var contactData = JSON.parse(raw);
     // only when Storage By Zapier not available 
     //var inputData  = JSON.parse(inputStore);

     // pull in data from Zapier
     //
     var contactData = JSON.parse(inputData.raw);
     //console.log(contactData);
     //console.log(inputData.secret);
     //var inputData = JSON.parse(inputData.testStore);
     //console.log(inputData.tags);
     //console.log(`inputData.tags: ${inputData.tags}`);

     //
     //  create output object to pass back to zapier after processing webhook from AgileCRM
     //
     //  receive raw webhook by parsing using built-in function
     //
