cosmos indexer: ERR Error getting block &{1296000 true false} from RPC

[risasoft]

I'm getting an error trying to connect with unicorn cosmos chain throught e cosmos indexer. I think it is issue in probe.

ERR Error getting block &{1296000 true false} from RPC. Err: error in json rpc client, with http response metadata: (Status: 200 OK, Protocol HTTP/1.1). error unmarshalling result: json: cannot unmarshal array into Go value of type map[string]json.RawMessage
^C

Here is my config file:

[base]
start-block = 1296000   # start indexing at beginning of the blockchain, -1 to resume from highest block indexed
end-block = -1   # stop indexing at this block, -1 to never stop indexing
throttling = 6.00
block-timer = 10000 #print out how long it takes to process this many blocks
wait-for-chain = false #if true, indexer will start when the node is caught up to the blockchain
wait-for-chain-delay = 10 #seconds to wait between each check for node to catch up to the chain
index-transactions = false #If false, we won't attempt to index the chain
exit-when-caught-up = false #mainly used for Osmosis rewards indexing
index-block-events = true #index block events for the particular chain
dry = false # if true, indexing will occur but data will not be written to the database.
rpc-workers = 1
reindex = true
reattempt-failed-blocks = false
