Whenever I try to get a raw transaction I get an error:

ubuntu@btc:~$ bitcoin-cli getrawtransaction 2157b554dcfda405233906e461ee593875ae4b1b97615872db6a25130ecc1dd6
error code: -5
error message:
No such mempool transaction. Use -txindex or provide a block hash to enable blockchain transaction queries. Use gettransaction for wallet transactions.

How can I fix this error?

  • Are you sure your node is using the bitcoin.conf? Have you tried enabling txindex using the CLI option? Jul 20 at 12:59
  • It does mention Config file: /mnt/btc/bitcoin/bitcoin.conf. I enabled it on command line an it now says error code: -5 error message: No such mempool transaction. Blockchain transactions are still in the process of being indexed. Use gettransaction for wallet transactions.

    Great, now you only need to wait for the indexing to finish and you'll have your txindex. In the meantime you can try to figure out why exactly your bitcoin.conf file isn't being read correctly. Jul 20 at 14:29
  • Where is your bitcoin.conf located? It looks like it is not parsing any of the other arguments in your conf file, otherwise there would be multiple Config file arg lines, but there's only one for the datadir.

  • I had 2. One was in ~/.bitcoin/bitcoin.conf that contained just datadir=/mnt/btc/bitcoin. In /mnt/btc/bitcoin/bitcoin.conf was the other one - that was not being read. So I moved the contents of it into ~/.bitcoin/bitcoin.conf. I am still unsure how to use a different conf file location.
