when the Polkadot runtime network is upgraded to an incompatible specification in the sidecar, do blocks with earlier spec numbers not get traced?
v17.3.1 is known to be compatible up to this specification number from the release notes.
However, the spec number naming in Polkadot has changed recently and it is hard to recognize. How do I read the spec version of a block tested in sidecar? https://github.com/paritytech/substrate-api-sidecar/releases/tag/v17.3.1
Hi @paperfrog1228 , I think there's a misunderstanding here. The compatibility refers to the client versions against which it was tested, while the spec_number refers to the runtime version and is set by the Polkadot Fellowship. You can check the difference and where you can see them in PJS/APPS here. So the version in the compatibility section refers to the node to which you connect sidecar.
Lastly, what's the request you are making that gives you that error? So that we can replicate it an see what's going on.
Description
Occur below error at block number 19550977.

The offending block has a spec number of 1000001. (https://polkadot.subscan.io/block/19550977)
However, the start time of the problem is ,
when it was upgraded from block 19551000 to 1001002. (https://polkadot.subscan.io/block/19550977)
Here's the question.
However, the spec number naming in Polkadot has changed recently and it is hard to recognize. How do I read the spec version of a block tested in sidecar?
https://github.com/paritytech/substrate-api-sidecar/releases/tag/v17.3.1
I don't know which spec number v10200 refers to.
Thanks in advance.
