There seems to be an error when sending the transaction

[CoderfishGzh]

When I execute the example of the trade function, an error occurs. What do I need to do to solve this problem

    Finished dev [unoptimized + debuginfo] target(s) in 3.63s

Is it a problem with my substrate version?

[haerdib]

Hm.. No, I don't think that's the substrate version. More like a mismatch between types. I'm not sure which example exactly you're using, but currently all examples are matched to the kitchensink_runtime. Which means they are using AssetTipExtrinsicParams, e.g. they depend upon the asset pallet. Is your runtime perhaps using the balances pallet? If so, try using PlainTipExtrinsicParams instead of AssetTipExtrinsicParams here:

substrate-api-client/examples/example_transfer_using_seed.rs

Lines 41 to 43 in 31a91d6

	let api = Api::<_, _, AssetTipExtrinsicParams>::new(client)
	.map(|api| api.set_signer(alice.clone()))
	.unwrap();

If possible, I would like our examples to use the PlainTip, which is the standard case. Is there no substrate docker image that comes with PlainTips?

[haerdib]

I'm currently thinking of a totally different solution: #344 (comment)

Maybe you know the answer to that: Is it possible to detect which tips to use, if the Runtime is known?

[haerdib]

And no, not as far as I know, but I haven't investigated much. I will, if #344 is not possible.

[haerdib]

#344 seems certainly possible, but it will take some time. I looked into the docker problem, but it seems parity does not upload the substrate node-template anymore (checked https://hub.docker.com/u/parity/),

[haerdib]

Closing this in favour of #383
