Discussion on: Building GraphQL APIs on Ethereum

[Friendly Tin Man]

Hi Nader!
The command "graph build" failed to compile data source mapping. This was caused by the error "Type 'Bytes' is not assignable to type 'string'."

This error pops up in two places:

1. inside mapping.ts function "handleTokenIPFSPathUpdated",
   entity.indexedTokenIPFSPath = event.params.indexedTokenIPFSPath

2. inside mapping.ts function "handleMinted",
   entity.indexedTokenIPFSPath = event.params.indexedTokenIPFSPath

How can I fix this issue?

I'm also getting this issue. Any updates on progress?
