  "code": 500,
  "message": "Cannot read properties of undefined (reading 'queryInfo')",
  "stack": "TypeError: Cannot read properties of undefined (reading 'queryInfo')\n    at BlocksService.fetchQueryInfo (/usr/src/app/build/src/services/blocks/BlocksService.js:243:46)\n    at runMicrotasks (<anonymous>)\n    at processTicksAndRejections (node:internal/process/task_queues:96:5)\n    at async BlocksService.fetchBlock (/usr/src/app/build/src/services/blocks/BlocksService.js:153:67)\n    at async BlocksController.getBlockById (/usr/src/app/build/src/controllers/blocks/BlocksController.js:152:49)\n    at async /usr/src/app/build/src/controllers/AbstractController.js:226:9",
  "level": "error"
}

Steps to Reproduce

See above links. If either of these blocks are included in a range query, the entire thing will also return a 500.

Expected vs. Actual Behavior

The block info should be correctly retrieved, just like all of the other blocks.

Okay cool, so for those public instances it looks like its an easy fix. They are currently on 14.5.2, they just need to be bumped to the most recent version: 17.0.0 and they should work fine.

I was able to confirm it locally

Thanks, it's been updated! Sorry for the noise.

Hi, I'm reopening this issue because I'm seeing a 500 error on a new range of blocks and I understand the sidecars are on the most recent release. Issues start at block 15976986 and end at block 15978187. Here is a sample error message:

{"code":500,"message":"Unable to decode storage session.validators:: createType([u8;21]):: [u8;21]:: Decoded input doesn't match input, received 0xa5040000966d74f8027e07b43717b6876d97544fe0d71facef06acc8382749ae…feffabd8f3747b5ca19766866bd59856a2e65c537c6456c6f6863c026915f473 (9506 bytes), created 0xa5040000966d74f8027e07b43717b6876d97544fe0 (21 bytes)","stack":"Error: Unable to decode storage session.validators:: createType([u8;21]):: [u8;21]:: Decoded input doesn't match input, received 0xa5040000966d74f8027e07b43717b6876d97544fe0d71facef06acc8382749ae…feffabd8f3747b5ca19766866bd59856a2e65c537c6456c6f6863c026915f473 (9506 bytes), created 0xa5040000966d74f8027e07b43717b6876d97544fe0 (21 bytes)\n    at RpcCore._newType (/usr/src/app/node_modules/@polkadot/rpc-core/cjs/bundle.js:385:19)\n    at RpcCore._formatStorageData (/usr/src/app/node_modules/@polkadot/rpc-core/cjs/bundle.js:320:21)\n    at RpcCore._formatOutput (/usr/src/app/node_modules/@polkadot/rpc-core/cjs/bundle.js:285:25)\n    at RpcCore._formatResult (/usr/src/app/node_modules/@polkadot/rpc-core/cjs/bundle.js:147:20)\n    at callWithRegistry (/usr/src/app/node_modules/@polkadot/rpc-core/cjs/bundle.js:168:25)\n    at processTicksAndRejections (node:internal/process/task_queues:96:5)","level":"error"}

The nodes it's connected to are on 0.9.43, the latest polkadot release.

Thanks for any help!
