ValueError: too many values to unpack (expected 1)

[andashologu]

Hello there I have created a python file that I can use to send a message to my own ID, I get this error below. When i trace back the error I find it to be in the _client.py file. I have figured out the problem but I dont have solution.

from line 48 to 58 of the _client.py file we have this code below

for x in j:
    if "error_results" in x:
        del rtn[-1]
        continue
        _util.handle_payload_error(x)
    [(key, value)] = x.items()
    _util.handle_graphql_errors(value)
    if "response" in value:
        rtn[int(key[1:])] = value["response"]
    else:
        rtn[int(key[1:])] = value["data"]

which result in this error

[(key, value)] = x.items()
ValueError: too many values to unpack (expected 1)

I found out that the error itself is supposed to be variable 'x' is not defined. I tried to look what variable 'x' is defined to, before it can used. Before line 48 I did not see anything defining x, x is not even visible before line 48, but in line 48 and onwards x is used to perform tasks without x being defined

my question now is , what is the value of x ?

Check ful error l below , and please help me out:
