Uncaught Error: Assertion failure AND Uncaught undefined DCPError: no transports defined

Bug Description

With this code:

#!/usr/bin/env python3
import pythonmonkey as pm
dcp_client = pm.require('dcp-client')

# define the data your workfunction will operate on
lst1 = []
lst2 = []

arr_size = 2500
#arr_size = 5000
#arr_size = arr_size / 2 + arr_size / 4 + arr_size / 8 + arr_size / 16
arr_size = int(arr_size)
print(arr_size)

for i in range(arr_size):
    lst2.append([])
    for j in range(arr_size):
        lst2[i].append(i + j + (j + 0.1) / (i + j + 0.123456))
    lst1.append(i * i)

args2 = [lst1, lst2]

data = [1, 2, 3, 4, 5]

# function which will execute on each datum in the dataset remotely on dcp workers
work_function = """
function myEpicWorkFn(datum, arg1, arg2)
{
    progress();
    return arg1.length + arg2.length; + datum
}
"""

async def pringle(): 
    dcp = pm.globalThis.dcp
    # define the compute workload (job)
    job = dcp.compute['for'](data, work_function, args2)

    # add event listeners for debug logs
    job.on('readystatechange', print)
    job.on('accepted', lambda: print(job.id))
    job.on('result', lambda x: print(f'New result for slice "{x.sliceNumber}" is "{x.result}"'))
    #job.computeGroups = [{ 'joinKey': 'joseph', 'joinSecret': 'pringle' }]

    # deploy the compute workload to the DCP network
    results = await job.exec()
    print(results)

dcp_client['init'](pringle)

sometimes I get

then with this last one later get

both messages come repeatedly

Uncaught undefined DCPError: no transports defined

was seen before and thought to be about the string corruption, so one out

Possibly also the other issue is caused by string corruption issue
