invalid json response body on getInvoicePdf

[pixelpaulaus]

the getInvoicePdf function seems to return an error when used...

{ FetchError: invalid json response body at https://sandbox-quickbooks.api.intuit.com/v3/company/4620816365004703610/invoice/162/pdf?minorversion=40 reason: Unexpected token % in JSON at position 0 at /home/dev/apdible/qbcustomerportalback/node_modules/node-fetch/lib/index.js:272:32 at <anonymous> at process._tickCallback (internal/process/next_tick.js:188:7) message: 'invalid json response body at https://sandbox-quickbooks.api.intuit.com/v3/company/4620816365004703610/invoice/162/pdf?minorversion=40 reason: Unexpected token % in JSON at position 0', type: 'invalid-json' }
