Random timeout errors when calling views_publish

Description

Recently started seeing random timeout errors while calling views_publish on webclient. Everything was fine until a few days ago. I checked with the slack support team as I suspected something to do with the API, they were not able to replicate the same with the API and suggested that I raise the issue here as I was using the python client.

Reproducible in:

slackclient version: slackclient==2.5.0 python version: python 3.7 OS version(s): Ubuntu

Steps to reproduce:

1. Call this views_publish on a json with about ~30 blocks close to 10 times at least one of them fails with a timeout. Sample code

import slack
bot_oauth_token = ''  # Add valid bot_token
client = slack.WebClient(token=bot_oauth_token)

client.views_publish(**j)

Expected result:

No request should fail with a timeout

Actual result:

Thanks for the quick response. I upgraded the slackclient on my local and ran my snippet 10 times and got no timeout. 😃 I’m upgrading the version on my production and will keep an eye out there as well, should get to know the results of that within a day as I was getting frequent timeouts there as well. Will post here once resolved. Thanks!
