Error with start page: 'FavaLedger' object has no attribute 'price_map'

I have installed this plugin, but I'm running into an error when I launch the fava application. When I click the Portfolio Summary link, I get the following error in the backend:

  ^^^^^^^^^^^^^^^^^^^^^^^^^

Here are the list of dependencies I am using:

beancount                 2.3.6
beancount-import          1.3.5.post1.dev50
beanprice                 1.2.0
fava                      1.27.2

Looks like 'price_map' has been changed to 'prices': https://github.com/beancount/fava/commit/4cdff4d13f0b2ff8dcb506695035ca3d2b42a330

Looks like more than just that:

The above exception was the direct cause of the following exception:

I was able to get this work by hacking the following:

__init__.py:

Change line to g.ledger.prices._map:
        self.irr = IRR(self.ledger.all_entries, g.ledger.prices._map, self.operating_currency, errors=self.ledger.errors)

Change the query to follows. My naming conversion of Dividends is like Assets:Fidelity:401K:Dividends:VTI, etc so that I can group all the various tickers under dividends in the Balance sheets etc. So maybe you can relax the query condition a little?
        query = (
            f"SELECT SUM(CONVERT(COST(position),'{self.operating_currency}')) AS dividends "
            #f"FROM HAS_ACCOUNT('{currency}') AND HAS_ACCOUNT('{parent_name}') WHERE LEAF(account) = 'Dividends'")
            f"FROM HAS_ACCOUNT('{currency}') AND HAS_ACCOUNT('{parent_name}') WHERE account ~ 'Dividends'")

Change the line:  need to add self.ledger.all_entries to the fava API
        result = self.ledger.query_shell.execute_query(self.ledger.all_entries, query)

PortfolioSummary.html

Change line to: remove the last_segment argument             
   {{ account_macros.account_name(ledger, row.account ) }}
