hey guys.i am doing some statistic on Tx infomation of the whole blockchain.so in order to eable a local rpc server,i set
Code:
server=1
txindex=1
and of course the user and passwd.
after doing this,i reindex  chainstate and start bitcoind with the option -txindex.but when i query transactions usually i get
Code:
example:bitcoin-cli getrawtransaction 2157b554dcfda405233906e461ee593875ae4b1b97615872db6a25130ecc1dd6 1
error code: -5
error message:
No such mempool transaction. Use -txindex to enable blockchain transaction queries. Use gettransaction for wallet transactions.

and what odd is that when i
Code:
bitcoin-cli getrawtransaction 8d0baa2c4d30e841e9b826ff8a99800032b112ca8368001e0e07fdeaa1fb4a2c 1
it returns txid vin vout,you konw, the right message.BTW,i didnt create any wallet.
i am curious about what happened here,and what can i do to get the Tx message i want.

Seems like that particular transaction wasn't indexed for some reason.
The configuration should be fine.

Try starting bitcoind with -reindex option to reindex the transactions again.

Is your node fully synced? What do you get from the getblockchaininfo command?

Both transactions seem to be from the same block with height 500000.

I personally have no problem getting the right response for both transactions though with bitcoin-cli so I'm not sure what is going on.

Sooner or later you're going to realize, just as I did, that there's a difference between knowing the path and walking the path

error message:

With txindex enabled the error message should be slightly different:

"No such mempool or blockchain transaction. Use gettransaction for wallet transactions."

getblockchaininfo result is fine

Code:
"chain": "main",
  "blocks": 540636,
  "headers": 541358,
  "bestblockhash": "000000000000000000086f70258ad16b5524fd43d287e5e2e01d33cb927f6277",
  "difficulty": 7019199231177.173,
  "mediantime": 1536486789,
  "verificationprogress": 0.9957173345534331,
  "initialblockdownload": true,
  "chainwork": "000000000000000000000000000000000000000003184707353223f933c61b83",
  "size_on_disk": 208170620396,
  "pruned": false,
........

i doubt that it could be a problem of the use of newest core vision?

right now i turn to use api provided by blockchaininfo website to query tx info.

Anything interesting in the debug.log file?

You should share the log here if there is anything suspicious about it.
Otherwise it would be a very weird problem.

Checked both on v0.16.2; both work fine

This. Clean your log, run both commands and copy the output of debug.log here.
