I keep seeing this error in console:
Uncaught Error: Callback was already called. at vendor.js:19 at vendor.js:19 at C3Request.childDataSourceLoadFailed (VM34211 application.js:8) at Collection.<anonymous> (VM34211 application.js:8) at Collection.<anonymous> (vendor.js:33) at Collection.<anonymous> (vendor.js:1) at h (vendor.js:33) at Collection.trigger (vendor.js:33) at Collection.onLoadFailure (VM34211 application.js:3) at C3Request.handleResponse (VM34211 application.js:8)
I believe it’s caused by calling the callback in
async more than once, possibly for retries!
This is preventing the childDataSource mapping from handling correctly the updates when a response if received.
How I can fix this issue?
