React - try catch of ledger.exercise issue

Questions

Hi, I’ve met some strange issue.

Here is my code snippet;
try {
await ledger.exercise(Main.Network.InviteCitizen, contractId, { … } )
} catch (error) {
console.log("error: " + error);
}

Issue is it always takes to catch with error. In my opinions, it happens because of error in ledger.exercise func. It says “Error: Trying to look up template 92332076d3b238b61e42ee43f7a2dc113348507827f7f86a6102e8013b5f247d:Main:CitizenInvitation.”

It’s very urgent and pls help me asap.

Thanks,
Alexander

Hi @alexander,

That usually arises if your codegen ends up in an inconsistent state somehow.
Take a look at my explanation at Warning message in JSON-API " Illegal header: Illegal 'origin' header: Illegal origin: Invalid input '/" and in particular the link to the steps in Daml-ui-template React function and Action with 2 arguments that should hopefully resolve your issue.

Hi, @cocreature Thanks for your fast response.

Actually I already tried as you mentioned in other ticket but it didn’t solve current issue :frowning:

Of course Warning message in JSON-API it’s related to current issue i think also.

The JSON-API warning is unrelated and only a warning (for now, it will turn into an error in future SDK version).
Did you see the suggestion to delete the yarn.lock as well at Daml-ui-template React function and Action with 2 arguments? Note that you should do that before running the other steps.

Okay let me try to follow your suggestion right now.

Still same. I removed yarn.lock & node_modules & yarn install with out any parameters but still same issue :frowning:

Not quite sure what could be going wrong there. Is your project available publicly somewhere?

9

Not available at the moment.

10

Which SDK version are you using and have you upgraded from a previous version or is this a fresh project? Also did it work at some point and things broke or did you always get this error.

11

I always get errors. And version of SDK is 1.1.1

12

Have you tried upgrading to 1.2.0?

I didn’t test it with 1.2.0

What is the function of daml codegen js -o daml2js daml/model/.daml/dist/*.dar?

15

It generates JS/TS files in the folder daml2js based on the types defines in the DAR file daml/model/.daml/dist/*.dar.

16

Where is daml/model located ? I am on ubuntu at the moment.

17

If you do not have a daml/model folder in your current working directory, there is little chance of that command working. Where did you get the command from? In general, you can expect the .daml/dist folder to be created by the daml build command in the same folder where your daml.yaml file is.

After upgraded version, it’s fixed. Thanks :slight_smile:
