Error in query curve_info for cw20-bonding

[shiki-tak]

I tried cw20-bonding and got the following error.

❯ CURVEINFO='{"curve_info":{}}'
❯ wasmd query wasm contract-state smart $CONTRACT "$CURVEINFO" --output json 
Error: rpc error: code = InvalidArgument desc = Error calling the VM: Error executing Wasm: Wasmer runtime error: RuntimeError: unreachable: query wasm contract failed: invalid request

Conditions

• Only query "CurveInfo" will cause an error.
• Doesn't happen when "CurveType" is "Constant", but happens after "Buy" for "Linear" and "SquareRoot".(Before "Buy", no error occurs.)
• cw-plus v0.10.0
• wasmd v0.20.0

[maurolacy]

Interesting. It would be good if you provide the data you're using / a path for reproducing this.

Perhaps it can be encoded as a unit test, or in any case, an integration test.

[shiki-tak]

Thanks for your reply.
I got error when I set the "INIT" as follows.

In addition, I haven't tried all the different cases, but...
When decimals, reserve_decimals, scale = 6, there is no error even if the curve_type is square_root.

I think this may be an overflow when converting from our Decimal to rust-decimal' s Decimal. There's a panic there that we're not currently handling / avoiding.

Thanks for the report. We will fix this asap.

[ethanfrey]

ah, 18 decimals... this causes all kinds of math overflows.

Why do you use that (besides habit from Ethereum)?

I mean, 6 or 9 decimals seems to suffice for almost any project.
The smallest measurement I have seen in use in Ethereum is GigaWei (for gas prices), which effectively is 9 decimal places.
Bitcoin works on 8, and still seems to be fine with that, even with $60.000/BTC (and 16 satoshi to $0.01)

[maurolacy]

We can still avoid panic when converting, basically by checking / limiting the range of allowed values / decimal places.

[shiki-tak]

I don't have to plan to use 18 decimals.
I think a check or limit to avoid panic is sufficient.

[ethanfrey]

I fully agree... a readable error message to the user is always better than a panic.

Removing the error condition (precision limit) can be discussed if there is a clear need. We would need to eg use u256 internally for all calculations, which may be a good idea? But checks/limits are 💯 need

[ethanfrey]

btw, cw20-bonding was written like 1 year ago and just updated to match versions.
It could probably use some care and cleanup in general.
If you are planning to deploy something on this to production, it would be good to revisit it and feel free to raise issues (and PRs 😄 ) on any points that seem a bit questionable.

I think I have an outstanding issue to allow cw20 as the input tokens, not just native

Hello, i'm having the same issue. i'm working with U256...

Error calling the VM: Error executing Wasm: Wasmer runtime error: RuntimeError: unreachable: execute wasm contract failed" module=state

I am also having trouble executing a message on cosmwasm contract, and I am getting the same exact method in the OP:

Error: rpc error: code = InvalidArgument desc = Error calling the VM: Error executing Wasm: Wasmer runtime error: RuntimeError: unreachable: query wasm contract failed: invalid request

I am estimating the gas for a MsgExecute on a custom contract.
I've battle tested the contract locally and am at 90% test coverage, this only happens after the contract is deployed.

Is there any way to get a better error message or some stacktrace?

[rashid3011]

I am getting this error,
Error: rpc error: code = InvalidArgument desc = unable to resolve type URL /cosmwasm.wasm.v1beta1.MsgStoreCode: tx parse error: invalid request

for this setup command from cosmwasm document
RES=$(wasmd tx wasm store target/wasm32-unknown-unknown/release/cw_nameservice.wasm --from fred $TXFLAG -y)

can anyone help me out in resolving?

[dusterbloom]

Hi,
I am also getting the same error when trying to upload data to a contract from a .csv file

CREATE='{"create_graph_from_file":{"filepath": "../AllEdges_Test.csv"}}
wasmd tx wasm execute $CONTRACT "$CREATE" --from admin $TXFLAG -y

I get the following error:

Error: rpc error: code = InvalidArgument desc = failed to execute message; message index: 0: Error 
 calling the VM: 
Error executing Wasm: Wasmer runtime error:
 RuntimeError: unreachable: execute wasm contract failed: invalid request

[ethanfrey]

If you use a cosmwasm 1.0.0 (no more rc) VM, ie. wasmd 0.27 or something that imports it, there is help.

Add features = ["abort"] to cosmwasm-std in your Cargo.toml and rebuild the wasm file.
Then it will give you a better error message
