No recent versions appear in Crashlytics (was “HTTP error 403…”)

Question

Edit / Update:

This error "failed to download settings..." is probably not related to the missing info in Crashlytics since the error is maybe permissible? (Though worth mentioning the error sometimes says code=2 now and sometimes code=-5 )

Crashlytics is still not showing any recent versions. Most all of my users are on Version 1.1 build #267, and we are testing Version 1.2. The latest build in the Crashlytics dashboard is way out of date at #239.

At first I thought this was because we started using Firebase without upgrading to the Firebase version of Crashlytics, but upgrading to Firebase-Crashlytics didn't fix it.

Noticing this error now:

2018-07-27 15:07:06.093192-0400 Fobo[1742:525256] [Crashlytics:Crash] Unable to read identifier at path /var/mobile/Containers/Data/Application/4CB32502-DA04-403D-B32D-02FA641F983D/Library/Caches/com.crashlytics.data/com.mvsstudio.fobo/v3/processing/fe3f8bfbbf944c8bbd8c5e847100efe9

And the log stops sometimes with just this, no "submission successful" line:

But also sometimes ends like this:

Either way, no luck seeing any of the recent data show up in the dashboard.

Original Question:

Crashlytics isn't showing any of our recent versions, events or crashes in the dashboard. When the app initializes Crashlytics, there's this 403 error which would seem to suggest a bad API key or something:

2018-07-20 12:49:16.402064-0400 Fobo[6705:3539611] [Crashlytics] Version 3.10.5 (130)

Answer 1

I had absolutely the same response trying to connect Fabric/Crashlytics to my application:

[Fabric] failed to download settings Error Domain=FABNetworkError Code=-5 "(null)" UserInfo={status_code=403, type=2, request_id=5d6157a905d6cb2859e27e4e3ef8b000, content_type=application/json; charset=utf-8}

While having the same Fabric version as you did:

[Fabric] Initialized with kit versions: {
    "com.twitter.answers.ios" = "1.3.7";
    "com.twitter.crashlytics.ios" = "3.10.5";
    "io.fabric.sdk.ios" = "1.7.9";
}

The problem was that I've switched from one Fabric organization to another and missed one important file that required changes: Info.plist

According to this link from Fabric documentation, you must insert into your Info.plist files next snippet:

<key>Fabric</key>
  <dict>
    <key>APIKey</key>
    <string>**HERE_IS_YOUR_API_KEY_FROM_FABRIC_ORGANIZATION**</string>
    <key>Kits</key>
    <array>
      <dict>
        <key>KitInfo</key>
        <dict/>
        <key>KitName</key>
        <string>Crashlytics</string>
      </dict>
    </array>
  </dict>

API key of your organization can be found under https://fabric.io/settings/organizations or at the:

1. Log in;
2. https://fabric.io/
3. Top right corner (gear icon);
4. Organizations;
5. Select the one required and see two labels API key and Build secret .

Exmple of selected organization

Click any label and you'll get the key.
