Trouble passing variables to query

[Banjerr]

Howdy everyone.

I'm attempting to pass a variable into a query, but keep running into issues and I'm not sure exactly why.

My query looks like this...

let queryVar = client.variable('currentTags', 'String!', currentTags); // currentTags = 'camping OR green'
    console.log(queryVar); // echoes out the VariableDefinition, which looks correct
    client.send(gql(client)
      `query ($currentTags: String!) {
         shop {
           products(first: 5, query: $currentTags) {
             pageInfo {
               hasNextPage
               hasPreviousPage
             }
             edges {
               node {
                 id
                 title
                 options {
                   name
                   values
                 }
                 variants(first: 25) {
                   pageInfo {
                     hasNextPage
                     hasPreviousPage
                   }
                   edges {
                     node {
                       title
                       selectedOptions {
                         name
                         value
                       }
                       image {
                         src
                       }
                       price
                     }
                   }
                 }
                 images(first: 5) {
                   pageInfo {
                     hasNextPage
                     hasPreviousPage
                   }
                   edges {
                     node {
                       src
                     }
                   }
                 }
               }
             }
           }
         }
       }
     `, [queryVar]).then((res) => {
       console.log('res is ', res);
    });

But I keep getting issues like expected Hash to be a Array if I pass the variable like [{currentTags: currentTags}] and an error like Variable currentTags of type String! was provided invalid value if I pass the variable like above.

Any suggestions?
