Describe your question in detail.

I encountered a problem with serializing different types of arguments, and I can't figure it out for the second day!

I'm getting data from an exchange API, which generates different paths to perform a certain exchange.

And I receive the following data:

JSON Arguments:

It's specifically the arguments, I need to pass them to EntryFunction.natural.
The first thought is to check what types are specified in the ABI or in the module and apply them.

And here it is:

public entry fun router_entry<
        T0, T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18, T19, T20, T21, T22, T23, T24, T25, T26, T27, T28, T29, T30, T31
    >(
        arg0: &signer,           
        arg1: 0x1::option::Option<signer>,  
        arg2: address,
        arg3: u64,
        arg4: u8,
        arg5: vector<u8>,
        arg6: vector<vector<vector<u8>>>,  
        arg7: vector<vector<vector<u64>>>,   
        arg8: vector<vector<vector<bool>>>, 
        arg9: vector<vector<u8>>,  
        arg10: vector<vector<vector<address>>>,
        arg11: vector<vector<address>>,
        arg12: vector<vector<address>>,
        arg13: 0x1::option::Option<vector<vector<vector<vector< vector<u8> >>>>>,
        arg14: vector<vector<vector<u64>>>, 
        arg15: 0x1::option::Option<vector<vector<vector<u8>>>>, 
        arg16: address,
        arg17: vector<u64>,
        arg18: u64,
        arg19: u64,
        arg20: address
    )
    {
    }

And here I am starting to run into problems. I’ve tried many different options, searched for information on how to correctly serialize the data, but apparently I didn't search well, because I haven’t found anything.

Here’s an example of the data I get from the wallet:

I don't know how to solve this.

Can you help me figure out how to correctly form the arguments for the transaction?
