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

https://eu.api.novu.co/v1/events/trigger

 https://eu.api.novu.co/v1/events/trigger

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

Private Key I made more checks. Private Key format is correct, I copy/paste it from

AuthKey_XXX.p8

AuthKey_XXX.p8

AuthKey_XXX.p8

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

openssl ec -in AuthKey_XXX.p8 -text -noout

openssl ec -in AuthKey_XXX.p8 -text -noout

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

NarekOP•2/4/25, 8:02 AM

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

Pawan JainAPP•2/5/25, 7:27 AM

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•2/5/25, 8:34 AM

Thank you very much @Pawan Jain

NarekOP•2/17/25, 8:14 AM

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

Pawan Jain•2/23/25, 2:48 PM

@Narek

Apologies for delay in response

Pawan Jain•2/23/25, 2:49 PM

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

NarekOP•2/24/25, 2:29 PM

@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•2/24/25, 2:32 PM

New error means some progress

Can you please share the transactionIdtransactionId here?

NarekOP•2/24/25, 2:49 PM

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

Pawan Jain•2/24/25, 3:11 PM

@Narek

Looks like you have stored push tokens in incorrect format

Pawan Jain•2/24/25, 3:11 PM

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'
);

Pawan Jain•2/24/25, 3:12 PM

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'
);

Pawan Jain•2/24/25, 3:13 PM

there should be deviceTokensdeviceTokens field with array of string values

NarekOP•2/24/25, 3:15 PM

ok, I sent deviceTokendeviceToken as a string

@Narek, you just advanced to level 2!

Pawan Jain•2/24/25, 3:23 PM

Can you please update the valid deviceTokens field with array of string values

Pawan Jain•2/24/25, 8:12 PM

@Narek

Pawan Jain•2/24/25, 8:12 PM

Let me know if you still see any error

NarekOP•2/25/25, 5:40 AM

@Pawan Jain Unfortunately the result is same.

Pawan JainAPP•2/25/25, 10:40 AM

Thanks Narek, I will check the issue again

Pawan Jain•2/25/25, 8:52 PM

@Narek

Are you using any sdk to store device credentials?

NarekOP•2/25/25, 9:10 PM

@Pawan Jain No, I am sending API requests.

Pawan Jain•2/25/25, 9:41 PM

@Narek

Can you share the curl code snippet?

NNarek ok, I sent `deviceToken` as a string { "_id": "67bc824f65e0ca66fba75...

Pawan Jain•2/25/25, 10:35 PM

it should be deviceTokensdeviceTokens

You are sending deviceTokendeviceToken

NarekOP•2/26/25, 10:01 AM

@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

NarekOP•3/3/25, 7:10 AM

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

Senior•3/10/25, 1:20 AM

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

NarekOP•3/10/25, 6:53 AM

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

Pawan Jain•3/10/25, 8:24 AM

@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•3/10/25, 8:55 AM

@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•3/10/25, 4:13 PM

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

Pawan Jain•3/11/25, 6:53 PM

@Narek @Senior
DMed you
