A Substrate indexing framework

Hydra indexer uses a too old version of polkadot/api which does not work with my substrate project #470

I can't get Hydra to work with my substrate project, I have an error that I know happens when polkadot/api is not up to date.

I clarify that my substrate project works very well with polkadotjs app.

Here are my logs:

Hi. Looking at indexer's and processor's package.jsons, I see there is a fixed dependency on "@polkadot/api": "5.9.1". That is likely the cause of your problem.

There is a successor project to Joystream Hydra called Subsquid https://github.com/subsquid/squid . It should have better support for the newest Polkadot API and many other goodies. You can set it up in a similar way as Hydra (see Subsquid's docs for more info). Joystream project will also migrate from Hydra to Subsquid in the near future. Thus, this particular issue will not be fixed in this repo.
