asyncio and GET: Unexpected UTF-8 BOM

[afogarty85]

Update

My asyncio powered GET requestor is giving me issues today, but only for certain workItem requests that it makes.

It is not a particular workItem that is causing the issue. I can retrieve a single workItem and then run the same function again and get rejected with the error:

Unexpected UTF-8 BOM (decode using utf-8-sig): line 1 column 1 (char 0)

The line that triggers the error is: workItem = await resp.json() in this function:

async def getWorkItem(self, session, url):
    async with session.get(url, headers=headers) as resp:
        workItem = await resp.json()  <----------------- the problem
        workItem = pd.json_normalize(workItem['value'])
        workItem.columns = workItem.columns.str.replace(
            'fields.', '', regex=False)
        return workItem

How might I try to solve this decoding issue?
