Not able to submit transactions

I am not able to submit transactions on to cardano network , i am getting some unusual nonesense errors like the above

When i calculate transaction fee :

When i try to finally submit the transaction:

What cardano-cli version are you on? Did you grab the latest parameters?

cardano-cli query protocol-parameters \
    --mainnet \
    --out-file params.json

Also, make sure you are doing the transaction in 3 steps:
First, make sure to run a cardano-cli transaction build-raw without fee first.
Then use that to calculate the fee with cardano-cli transaction calculate-min-fee
Finally, build the transaction again with the included fee cardano-cli transaction build-raw and sign cardano-cli transaction sign then send it away to the blockchain

Hope that helps

looks like you are trying to get some parameter from params.json… the JSON key was not found… either you are pointing to the wrong or incomplete file.
it is hard to say, as I don’t see what you have in the file.
