Spec json is invalid: missing field eip1108_transition_base at line 65 column 181

You must be using latest parity version (2.6.3 or 2.5.8). Unfortunately, some breaking changes were introduced in these versions, and our current format of spec.json from our github repo is not currently accepted. We will upgrade our current nodes and spec in the near future, but for now you can either use previous version of parity (2.6.2 or 2.5.7) or (instead of pointing directly to file --chain /path/to/spec.json) use built-in spec for core/sokol/xdai with --chain poacore / --chain sokol / --chain xdai

Thanks.
I couldn’t find 2.6.2 on parity website, but I made up with 2.7.0.
