Wrong request. Error: The data couldn’t be read because it isn’t in the correct format when using Safe via walletconnect

The error is thrown when trying to call execTransactions with Safe (walletconnect):

here is the example app where you can reproduce this: https://github.com/gnosis/cpk-compound-example/blob/master/src/components/CompoundForm.tsx#L70

The error in the issue title was thrown when using safe rinkeby on iOS

on android the following error is thrown: Error: Could not handle custom call: java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.String

[mmv08]

In general it seems not to work with walletconnect: https://rinkeby.etherscan.io/tx/0xbd2ab441819d441ec43eca138ec5588935e5dafa01c53a4585f0b54b90c33ead

with metamask mobile the tx reverts, but it works with the same wallet but in an extension

For the linked transaction you run out of gas, up the gas limit

@cag issue is that operation for the multi send needs to be a string. Could this please be changed.

[mmv08]

The issue still persists. You should be able to reproduce it on master branch in https://github.com/gnosis/cpk-compound-tutorial/

This should be fixed as soon https://github.com/gnosis/safe-android/issues/540 is implemented, but we'll have to revert "pass operation as string" changes
