Issues with ./contrib/sidechain-manipulation.py after creating a New Sidechain about elements

[gwillen]

Hi @JJaouadi! It seems like the script is having trouble talking to your sidechain daemon (e.g. alphad). From the error you're getting, it reads to me like it successfully connected to the RPC port, made a request, and got a response, but the first line of the response was blank and did not contain an HTTP status code, OR possibly the sidechain daemon disconnected instead of providing a response.

Can you check and make sure that your sidechain daemon is running, that you can make requests to it successfully using bitcoin-cli/alpha-cli or equivalent, and can you check its log for suggestive errors?

I'm happy to walk you through any of those things.

Thank you very much for your response @gwillen :)

Hi ! After creating my sidechain, I followed Step 6 of the Elements-Alpha README to move money into my new sidechain. After the "claim-on-sidechain" part, I run blocksign.py but I have issues with spend-from-claim command can you help me please ?

@JJaouadi might be because the peg-in utxo was still too "new" for a free transaction.
