Sushiswap Exchange Goerli deployment

I'm trying to deploy a Goerli version of the SushiSwap Exchange Subgraph - https://github.com/sushiswap/sushiswap-subgraph/tree/master/subgraphs/exchange

When I build I get some warnings but no errors (sample below)

WARNING AS206: Compiling constant with non-constant initializer as mutable.
   const token1DayData = updateTokenDayData(token1 as Token, event)
         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 in src/mappings/pair.ts(658,8)

When I try to deploy I get the message

The current version of graph-cli can't be used with mappings on apiVersion less than '0.0.5'

After updating the apiVersion to 0.0.5 and deploying the following error appears

To use this version of the graph-cli you must upgrade the graph-ts dependency to a version greater than or equal to 0.22.0
Also, you'll probably need to take a look at our AssemblyScript migration guide because of language breaking changes: https://gist.github.com/otaviopace/8406cb39644d2e7678570d1e7f50dac4

(side note, that warning with a link to the migration guide is a 404 and should probably link to https://thegraph.com/docs/en/developer/assemblyscript-migration-guide/)

When I update the graph-ts to 0.22.0 the yarn build command fails with

✖ Failed to compile subgraph: Failed to compile data source mapping: Compile error

Am I right in assuming that someone need to go back through the mappings /entities and fix the breaking changes moving from 0.19.0 - 0.22.0?
