In my react front-end I am accessing the motoko backend functions by this line of code import { mytodo_backend } from "../../../declarations/mytodo_backend/index";
, locally everything is working fine and i can persist the data to the backend without any problem, but after deploying the front-end appears to just be working on its own and not connect to the backend at all. The project is a simple todo dapp. This is the link to my github repo of the project..
Is the @dfinity/agent
package on the latest version? It could be the same problem as in the same thread where calls don’t work to the old URL
The @dfinity/agent
package is latest I updated it but nothing have changed. But I just saw this error in the browser console on the deployed front front-end.
dex.js:2 Refused to connect to 'https://icp0.io/api/v2/canister/jz3aw-xqaaa-aaaal-qbyna-cai/query' because it violates the following Content Security Policy directive: "connect-src 'self' https://ic0.app https://*.ic0.app".
If I try to access my front-end at .ic0.app
I am getting 404 error. How can I fix this?
In your frontend assets/source you should find one or two files called .ic-assets.json
or .ic-assets.json5
. These contain content security policy headers that are most likely still only targeted at ic0.app
instead of icp0.io
. Replace those with the headers from the updated starter template here. Then, if you’re not on dfx 0.14 yet, redeploy your asset canister with --mode reinstall
to force-update the headers
Fixed, I just replaced those files and redeployed. Thank you so much.
