UFT-1398 Android wallets - Insufficient energy when casting a vote

Deploying locally all the components and trying to use the election dApp resulted with insufficient energy. I was trying to cast a vote with Concordium seedphrase wallet on Android 1.5.1 (70).

To reproduce:

1. Use the test script to deploy the election but comment out the voting function so that the script doesn't perform voting.
2. Run the election setup with min 5 nominees.
3. Build and deploy the dApp
4. Serve all the necessary files for the dApp.
5. Cast a vote with seedphrase wallet. Select candidate number 3.

Result:

Insufficient energy.

Expected result:

User should be able to cast a vote.

Note:

The issue is triggered if the number of nominees is 5. With 3 nominees, it is possible to cast a vote.

To reproduce issue with Test-bench:

1. Connect to test bench using wallet connect.
2. In the first case ((IP) Testing simple input parameters) select function: String.
3. In the input parameter paste the 60000 characters string that is in the file attached.
4. Select Set string value

Result:

Notice that at the time the signature page pops up in the wallet, there is a toast error message (communication error). The transaction fails, insufficient energy.

Expected:

Transaction passes successfully.

In this case energy assigned by the dApp should be used as the actual energy.
