Electrs: Error: An unknown argument '--jsonrpc-import' was specified.

[openoms]

A new issue has occured when running on the RaspiBlitz, confirmed by multiple other users too: https://github.com/openoms/bitcoin-tutorials/issues/11
HW: RPi4 4GB
OS: Raspbian Buster, RaspiBlitz 1.3, bitcoind 0.18.1.

After a succesful build with https://github.com/openoms/bitcoin-tutorials/blob/master/electrs/1_electrs_on_RaspiBlitz.sh
Using the command:
./home/admin/electrs/target/release/electrs --index-batch-size=10 --jsonrpc-import --db-dir /mnt/hdd/electrs/db --electrum-rpc-addr="0.0.0.0:50001" --cookie="raspibolt:PASSWORD_B" -vvvv

Results to an error:

Error: An unknown argument '--jsonrpc-import' was specified.

Is there any known way to solve this?

Taking a look now, thanks for reporting!

[romanz]

First of all, sorry for the breakage!
This is probably a side effect from https://github.com/romanz/electrs/issues/151#issuecomment-528757361 - we meant to fix a security issue but didn't communicate well the reason behind it in the latest (unofficially) released version.

[romanz]

1. Using --jsonrpc_import instead of --jsonrpc-import seems to work.
2. --cookie is now not supported via command-line, to prevent potential security issues (see https://github.com/romanz/electrs/issues/151) - but can be specified via a config file.

CC @Kixunil could you please take a look on the 1st issue (--jsonrpc_import-related)?

[romanz]

You should be able to use the following electrs.toml config file for setting the flags (including cookie):

verbose = 4
timestamp = true
jsonrpc_import = true
db_dir = "/home/user/.electrs/"
cookie = "username:password"

Make sure that the config file is in the current working directory of electrs.

[romanz]

In order to prevent such issues in the future, would you like for me to open a GitHub issue for announcing backward incompatible issue?
We can also use https://gitter.im/romanz/electrs for coordination, if you prefer.
@openoms @victorscones @Kixunil WDYT?
(please CC other users of electrs who may be interested...)

[openoms]

ok, thanks. Will try to apply the fix shortly and will update my guide.

[openoms]

Trying to find out where to put this electrs.toml
what would be the working direcory in our case when running: /home/admin/electrs/target/release/electrs ?
tried /home/admin/electrs/target/release/, /home/admin/electrs/, /home/admin/electrs/src so far to no avail

[romanz]

IIUC, you can put it also under /etc/electrs/config.toml or ~/.electrs/config.toml.
If it doesn't work, please let me know and I'll update the docs.

[openoms]

Thank you, my server is up again. The ~/.electrs/config.toml worked. The RaspiBlitz guide is updated too.

[Kixunil]

Sorry, I was pretty busy and didn't notice this. Glad it's resolved! Will release new version of configure_me ASAP to fix hypen issue. (But config files are better for this stuff anyway. :P)
