The `sendTransfer` method displays `no such schema </tag>`

[d-yokoi]

Hi, I'm learning ILP with the document(https://interledger.org/tutorials/letter-shop/).

In Step 3: Paying for a letter, I executed pay.js script to make payment but sendTransfer method unexpectedly displays no such schema </tag>.

Please tell me what is the correct behavior and how to fix this.

Thanks.

It seems that problem is the version of jsonschema.
Have a try with
npm i jsonschema@1.2.2
then execute pay.js
