How do I get the storage value of a bigmap using pair datatype as key with taquito library?

Question

I am using the taquito library to interact with a smart contract that I have uploaded to carthagenet.

However, I am facing an issue in retrieving the value of a bigmap property in my smart contract storage with pair datatype as the key.

I have tried the following method and it doesn't work.

// agreements is a property in my storage with bigmap datatype

const bigMapValue = await storage.agreements.get({0:userAddr, 1: senderAddr});

The error that was thrown

Unable to encode big map key: TypeError: this.bigMap.KeySchema.ToBigMapKey is not a function

Thanks for using Taquito. Using a pair as a key is not yet supported in Taquito. We created this issue github.com/ecadlabs/taquito/issues/251 to track. Can you reach out to me as I'd like to get some more details about your use-case. — Jev Björsell, Feb 6, 2020 at 15:25

As of Taquito release v6.1.0-beta.0 Taquito offers a new API for Maps which support pairs as keys in Maps and BigMaps.

Here's a link to documentation & examples on Accessing Map values using Pairs
