IOS - Error: an unknown error occured for whats app stickers

[ibrahim5511]

This is my code:
sendPack () {
if(this.state.isAvailable == false){
return Alert.alert('whatsapp is not available');
}
const { stickers, ...packConfig } = stickerConfig;
if (Platform.OS === 'ios') {
return RNWhatsAppStickers.createStickerPack(packConfig)
.then(() => {
const promises = stickers.map(item =>
RNWhatsAppStickers.addSticker(item.fileName, item.emojis)
)
Promise.all(promises).then(() => RNWhatsAppStickers.send())
})
.catch(e => console.log(e))
}

stickerConfig.js:
export const stickerConfig = {
identifier: 'myprojectstickers',
name: 'myprojectstickers',
publisher: "info@company.com", // i'm adding my real email
trayImageFileName: 'tray.png',
publisher_email: "info@company.com", // i'm adding my real email
publisherWebsite: 'https://website.com/', // i'm adding my real website
stickers: [
{
fileName: "sticker1.webp",
emojis: ['😎'],
},
{
fileName: "sticker2.webp",
emojis: ['😎'],
},
{
fileName: "sticker3.webp",
emojis: ['😎'],
},
]
}

I'm placing my folder containing the stickers(myprojectstickers) in the same directory of my stickerConfig file, and I drag it to Xcode as mentioned to do.
I'm getting the following error only on IOS: Error: an unknown error occured for whats app stickers
Error is occurring when creating the sticker pack.
Knowing that I'm following IOS stickers guidelines.
Any help please? Thank you in advance.
