Explorer can't start, Error: Parse error

[sfoxdev]

Hello,
I'm trying to start explorer for coin BIT (https://github.com/bitcf/bitcf/releases), but get such error:

explorer@1.6.1 start /srv/explorer
node --stack-size=10000 ./bin/cluster

What does this code mean 32700? Where I can find list of error codes?

[sfoxdev]

Thanks @erfan007p

-32700 | Parse error | Invalid JSON was received by the server.An error occurred on the server while parsing the JSON text.

Does it mean that coin returns from rpc wrong json format?
How can I view output from rpc server or debug to solve this issue?

[erfan007p]

curl --user rpcuser:rpcpassword --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }' -H 'content-type: text/plain;' http://localhost:rpcport/

[sfoxdev]

I get correct answers from rpc using commands getinfo, getdifficulty, getmininginfo, getconnectioncount, getblockcount.
Here is sample output for getinfo:

curl --user test:test --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }' -H 'content-type: text/plain;' http://localhost:16662/

Does it mean that problem in explorer? If yes, than how can I solve this issue?

[erfan007p]

Try to disable API

[sfoxdev]

I have tried and get the same error.

[erfan007p]

Check your rpcuser and rpcpassword, make sure it matched settings.json

[sfoxdev]

Checked, they are matched.
Wrong user or pass give other error: { [Error: Invalid params, response status code: 401] code: -32602 }

[bigwavedave42]

Were you able to solve this? I've been seeing the same error, but curl tests look fine.

curl test :
$ curl --user user:password --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:3699/ {"result":{"version":"v1.2.0.4-ge0b1f06","protocolversion":60004,"walletversion":60000,"balance":0.00000000,"newmint":0.00000000,"stake":0.00000000,"blocks":348160,"moneysupply":9020227.00821400,"connections":120,"proxy":"","ip":"99.99.99.99","difficulty":4046.11428485,"testnet":false,"keypoololdest":1517130110,"keypoolsize":102,"paytxfee":0.01000000,"errors":""},"error":null,"id":"curltest"}

Unfortunately NO, I moved to use other explorer.

[Doppelgangerhef]

@sfoxdev What other explorer did you move to? I'm running into this same issue.

@iquidus do you have any insight to what this error could be?

Thanks!

[sfoxdev]

@Doppelgangerhef https://github.com/Valermos/emercoin-blockchain-explorer - I've modified this explorer to my needs and it works great with my coin.

[Doppelgangerhef]

@sfoxdev I'll take a look at it, thanks!

ANyone knows how to solve this please ?
