Failed to generate token: secretOrPrivateKey must be an asymmetric key when using ES256

I have an iOS mobile application (https://apps.apple.com/us/app/ferienhausmiete/id6475052679) generated by PWABuilder. I setup Novu for sending push notifications via APNs provider. I am sending POST request to https://eu.api.novu.co/v1/events/trigger with PostMan and getting this response { "data": { "acknowledged": true, "status": "processed", "transactionId": "29861fe0-f8c5-4126-9f03-fc56e97e9eb4" } } but in Activity Feed page I have an Error (check the screenshot). I have double checked Key ID, Team ID, Bundle ID. With Private Key I made more checks. Private Key format is correct, I copy/paste it from AuthKey_XXX.p8 file (including -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY----- parts), I verified it with openssl ec -in AuthKey_XXX.p8 -text -noout command and the result was like this read EC key Private-Key: (256 bit) priv: XX:XX:XX... pub: XX:XX:XX... ASN1 OID: prime256v1 NIST CURVE: P-256 which means that everything is correct. On application side everything looks correct, after instalation I am asking for a permision to send notifications. Please help me to figure out with this problem. Let me know if you need more information/data to help me. Thanks in advance.

@Narek Thanks for sharing the details. I will look into this and will update

Hi @Pawan Jain , had you chance to check my case, thanks in advance

Pawan Jain•2mo ago

Hey Narek

I did check this from my end. APNS Integration credentials is correct. I have applied for apple developer account so that I can test the apns integration with my credentials. I will keep you updated

NarekOP•2mo ago

Thank you very much @Pawan Jain Hi @Pawan Jain , have you some progress for this or maybe any suggestion how can I try some other way to fix this problem? I have tried to update the Private Key also via API requests, as I saw there was such problem a long times ago, but the result is same and I really stacked with this. With Android everything goes very smooth and I want to have the same result with iOS too 🙂 .

@Narek Apologies for delay in response

Pawan Jain•2mo ago

Can you check if your key is enabled for production environment if you have switched on production option in apns integration form

NarekOP•2mo ago

@Pawan Jain It was switched off. I turned it on and tried to send a notification. It failed again, but the error message is different now.

Pawan Jain•2mo ago

New error means some progress 😀 Can you please share the transactionId here?

NarekOP•2mo ago

@Pawan Jain Agree))) Transaction ID 9eaeb524-78f2-4b40-b7fb-11babd1870df

@Narek Looks like you have stored push tokens in incorrect format correct format for FCM 👇🏻

await novu.subscribers.setCredentials(
  'subscriberId',
  PushProviderIdEnum.FCM, {
    deviceTokens: ['token1', 'token2']
  },
  'fcm-MnGLxp8uy'
);

await novu.subscribers.setCredentials(
  'subscriberId',
  PushProviderIdEnum.FCM, {
    deviceTokens: ['token1', 'token2']
  },
  'fcm-MnGLxp8uy'
);

Correct format for APNS 👇🏻

await novu.subscribers.setCredentials(
  'subscriberId',
  PushProviderIdEnum.APNS, {
    deviceTokens: ['APNS_token1', 'APNS_token2']
  },
  'APNS-_intetegration_identifier_nGLxp8uy'
);

await novu.subscribers.setCredentials(
  'subscriberId',
  PushProviderIdEnum.APNS, {
    deviceTokens: ['APNS_token1', 'APNS_token2']
  },
  'APNS-_intetegration_identifier_nGLxp8uy'
);

there should be deviceTokens field with array of string values

NarekOP•2mo ago

ok, I sent deviceToken as a string { "_id": "67bc824f65e0ca66fba75862", "_organizationId": "aaaa", "_environmentId": "aaaa", "subscriberId": "404", "channels": [ { "providerId": "fcm", "credentials": { "deviceToken": "cG9RJgVcYawcRYDJmZ0CBC:AP...." } } ], "data": { "user_id": 111111 }, "deleted": false, "createdAt": "2025-02-24T14:29:35.324Z", "updatedAt": "2025-02-24T14:29:35.324Z", "__v": 0 },

@Narek, you just advanced to level 2!

Pawan Jain•2mo ago

Can you please update the valid deviceTokens field with array of string values @Narek Let me know if you still see any error

NarekOP•2mo ago

@Pawan Jain Unfortunately the result is same. Transaction IDs: c0fcc02c-2228-4863-a27c-2643c22ed405 a3c1ea60-7fe1-4701-87f8-4335515b139f I just updated all subscribers and tried to send notification to Android and again got an error. Here are the transactionIds f1cc4926-39ae-4d4e-ae42-1eb495913a5c 4dad0fc9-2f96-43df-a71b-96b8b2312871

Pawan Jain•2mo ago

Thanks Narek, I will check the issue again

Pawan Jain•2mo ago

@Narek Are you using any sdk to store device credentials?

NarekOP•2mo ago

@Pawan Jain No, I am sending API requests.

Pawan Jain•2mo ago

@Narek Can you share the curl code snippet? it should be deviceTokens You are sending deviceToken

NarekOP•2mo ago

@Pawan Jain I've updated all subscribers with correct format. With Android everything is ok, but for iOS I have the same error. Here are the TransactionIDs 80fe4228-8a89-4932-9354-402c7265c3d5 109b2f90-9db9-4369-812c-c1f0b37209ae

Hi @Pawan Jain , had you chance to check my case?

Senior•4w ago

Hello i'm getting the initial error you shared even after switching on the 'production' option. Any idea ?

NarekOP•4w ago

Not yet, I am still waiting for some response from @Pawan Jain

Pawan Jain•4w ago

@Narek @Senior Can you share if you are using swift based iOS application or expo based iOS application? I am interested in how the device token is generated.

NarekOP•4w ago

@Pawan Jain My application is swift based. I am using https://www.pwabuilder.com/reportcard?site=https://ferienhausmiete.de/ to generate package of my application. I am running this package with Xcode, making some edits (including changes for push notifications) and publishing it from Xcode directly to AppStore.

@Narek, you just advanced to level 3!

Senior•4w ago

Thanks for the reply @Pawan Jain i'm using bare workflow react-native iOS application. if the error is caused by the device tokens, I could try to correct and use different ones. I assumed the error is related to the authentication with APNS api
