Help for requestSignTransactions

How do I call the requestSignTransactions?

I am trying to call the nft_mint action on a contract. Here is the code I am trying but it is not working.

  const response = await walletConnection.requestSignTransactions({
    callbackUrl: `http://localhost:3000/callback`,
    transactions: [
      new nearAPI.transactions.Transaction({
        receiverId: my_contract_address,
        actions: [
          {
            functionCall: {
              args: new TextEncoder().encode(
                JSON.stringify({ collection_id: 123 }),
              ),
              deposit: new BN(parseNearAmount('15') || 0),
              gas: new BN(100000000000000),
              methodName: 'nft_mint',
            },
          },
        ],
      }),
    ],
  });

Any help would be appreciated

Turns out the issue from our end itself.

Once user is redirected to out platform after clicking on "connect", we need to immediately connect the wallet. I think the near-api-js needs the query params returned by the wallet to make a connection.

This needs to be documented somewhere.
