lightning community – EstimateFee – Invalid Size Vacation spot Key

Background
I’ve setup a regnet check community with two LND nodes. One to ship cash and the second (lnd2) to generate invoices on. I’m writing code to simulate a cell app. I am presently attempting to calculate the price to pay an bill and trying to name /v2/router/route/estimatefee

I am getting this error once I execute the code beneath:
{‘code’: 2, ‘message’: ‘invalid size vacation spot key’, ‘particulars’: []}

I am going to admit the byte to uncooked to decode has me a bit confused. However I am unsure I am feeding the right tackle.
