Lucid library (cardano blockchain) fail to initialize
I am trying to initiliaze a library called lucid (npm install lucid-cardano) and it is erroring out- docs can be found here (https://lucid.spacebudz.io/).
code that want to be implemented:
<
"use node"
import { action } from "./_generated/server";
import { Blockfrost, Lucid } from "lucid-cardano";
export const doSomething = action({
handler: async () => {
const lucid = await Lucid.new( new Blockfrost("https://cardano-preprod.blockfrost.io/api/v0", "hdhdhddhdfhdhf"), "Preprod", );
}, }); > Error that i am getting: < Uncaught Failed to analyze _deps/node/KYCSLYXW.js: ENOENT: no such file or directory, open '/var/cardano_multiplatform_lib_bg.wasm' >
const lucid = await Lucid.new( new Blockfrost("https://cardano-preprod.blockfrost.io/api/v0", "hdhdhddhdfhdhf"), "Preprod", );
}, }); > Error that i am getting: < Uncaught Failed to analyze _deps/node/KYCSLYXW.js: ENOENT: no such file or directory, open '/var/cardano_multiplatform_lib_bg.wasm' >

sometimes the bundler can't detect all files you need to run certain npm packages, so it doesn't include files like .wasm read from the filesystem. To avoid this error, you can include lucid-cardano as an external dependency https://docs.convex.dev/functions/bundling#external-packages

thnaks Lee, it worked!
thanks Lee, i am just starting to use Convex, and i am encountering an early mistake. Within the same file i am trying to declare this mutation and action, but i am having a type error. what could be wrong? i could not figure it out.
<>
<import { action, mutation } from "./_generated/server";
import { v } from "convex/values";
export const doSomething = action({
args: { a: v.string() },
handler: async (ctx, args) => {
await ctx.runMutation(createTask, { text: args.a, }); return "success"; }, }); const createTask = mutation({ args: { text: v.string() }, handler: async (ctx, args) => { await ctx.db.insert("teste", { text: args.text }); }, });>
await ctx.runMutation(createTask, { text: args.a, }); return "success"; }, }); const createTask = mutation({ args: { text: v.string() }, handler: async (ctx, args) => { await ctx.db.insert("teste", { text: args.text }); }, });>
when calling runMutation the first argument is a fully qualified function reference, like
api.filename.createTaskah ok got it. so for runMutatio is either internal or api for getting a fully qualified function reference.
now it is working, thanks a lot
HI, Lee, i have doubt regarding File Storage. Is there any difference between the follwoing two methods to obtain the url of a file stored at convex:
1. getting the URL using convex URL + storageID (convexURL/api/storage/{storageId}
2. getting the URL from ctx.storage.getUrl
can i used them interchangably at my convenience?
or is there points that i should take into consideration for each method?
yes the difference is that (1) doesn't work. Was there any documentation you saw that indicated it would work?

yep that's the tutorial mentioned in @presley 's message
sorry about the confusion
So does it work? Or should I only use the second method?
it does not work, so you should only use the second method
