由 荒凉一梦 提交于 2019-12-10 02:09:44
问题 Since this morning, our Firebase application has a problem when writing data to the Realtime Database instance. Even the simplest task, such as adding one key-value pair to an object triggers Error: TRIGGER_PAYLOAD_TOO_LARGE: This request would cause a function payload exceeding the maximum size allowed. It is especially strange since nothing in our code or database has changed for more than 24 hours. Even something as simple as Database.ref('environments/' + envkey).child('orders/' +

问题 I have an Angular web app that uses Firestore for data. In Chrome, Firefox and Safari everything is working as expected. I've opened the app on Microsoft Edge and it's taking up to 30 seconds to fetch a collection of 4 items.

The detail page has the same data and another 4 pieces of metadata, all of which are

How do I get the current user's access token in AngularFire2?

由 烈酒焚心 提交于 2019-12-09 05:32:44
问题 In AngularFire you were able to access the providers (e.g Google) accessToken for the authenticated user. There does not seem to be a way to access this with AngularFire2?

And the accessToken is not an accessible property? Is there a way
