BulkOperation Response is null when creating Products in Shopify App in nodejs

Hey, Community I Hope So You all are fine!
I am developing an app to import large amounts of products from kinguin platform to the Shopify app.
When I create a BulkOperationRunMutation for productCreate it returns the following response:

the bulk operation has NULL Value…
Following is the code for it:

const BULK_OPERATION = mutation RunBulkMutation($mutation: String!, $stagedUploadPath: String!) { bulkOperationRunMutation(mutation: $mutation, stagedUploadPath: $stagedUploadPath) { bulkOperation { id url status } } }

try {
const resp = await client.query({
data: {
query: BULK_OPERATION,
variables: {
mutation: mutation call($input: ProductInput!) { productCreate(input: $input) { product { id } } },
stagedUploadPath: “tmp/21759409/bulk/2d278b12-d153-4667-a05c-a5d8181623de/bulk_op_vars” }
},
});
console.log(resp.body)
} catch (error) {
if (error instanceof GraphqlQueryError) {
throw new Error(
${error.message}\n${JSON.stringify(error.response, null, 2)}
);
} else {
throw error;
}
}
Please Tell Me About It if anybody Knows!
Thanks in advance!
