Django app with Azure storage account - images are not saved to blob storage container - Stack Overflow

I have a Django app, and I am trying to store images in an Azure Storage account. I have a database with table category and property name images, where the URL of the uploaded image is saved when a user uploads an image. For example:

media/photos/categories/Koesimanse.png

However, the image is not being saved in the Azure storage container. When I try to access the URL:

.jpeg 

Then I get this error:

BlobNotFound The specified blob does not exist. RequestId:2bf5ff31-201e-0066-459e-a4a58e000000 Time:2025-04-03T13:45:48.5890398Z

Additionally, when I check the blob container, the image is not there.

However, if I manually upload an image to the Azure blob container and store its URL in the database, the image is successfully retrieved from Azure Storage blob container.

So for the models I have this:

class Category(models.Model):
    name = models.CharField(max_length=100, unique=True, verbose_name="Naam")
    description = CKEditor5Field(
        max_length=11000,
        blank=True,
        null=True, 
        verbose_name="Beschrijving",
        config_name="extends")
    images = models.ImageField(
        upload_to="media/photos/categories", blank=False, null=False, verbose_name="Foto")
    # Define the cropping field
    cropping = ImageRatioField('images', '300x300')
    category = models.ForeignKey("Category", on_delete=models.CASCADE,
                                 related_name='subcategories', blank=True, null=True, verbose_name="Categorie")
    date_create = models.DateTimeField(
        auto_now_add=True, verbose_name="Datum aangemaakt")
    date_update = models.DateTimeField(
        auto_now=True, verbose_name="Datum geupdate")

    def img_preview(self):
        if self.images and self.images.name:
            try:
                if self.images.storage.exists(self.images.name):
                    print("IMAGES SAVED")
                    print(self.images)
                    return mark_safe(f'<img src = "{self.images.url}" width = "300"/>')
                else:
                    return "No image"

            except ResourceNotFoundError:
                return "No image availble"

    img_preview.short_description = "Huidige Foto"

    class Meta:
        managed = True
        verbose_name = "Categorie"
        verbose_name_plural = "Categoriën"

    def save(self, *args, **kwargs):

        if self.images:
            self.images = process_image(self.images)

        super().save(*args, **kwargs)

    def __str__(self):
        return self.name

And for azure storage I have this file custom_azure.py:

from storages.backends.azure_storage import AzureStorage


class AzureMediaStorage(AzureStorage):
    # Must be replaced by your <storage_account_name>
    account_name = 'dier'
    # Must be replaced by your <storage_account_key>
    account_key = ''
    azure_container = 'media'
    expiration_secs = None


class AzureStaticStorage(AzureStorage):
    # Must be replaced by your storage_account_name
    account_name = 'dier'
    # Must be replaced by your <storage_account_key>
    account_key = ''
    azure_container = 'static'
    expiration_secs = None

and settings.py:

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

DEFAULT_FILE_STORAGE = 'Dieren.custom_azure.AzureMediaStorage'
STATICFILES_STORAGE = 'Dieren.custom_azure.AzureStaticStorage'

STATIC_LOCATION = "static"
MEDIA_LOCATION = "media"

AZURE_ACCOUNT_NAME = "dier"
AZURE_CUSTOM_DOMAIN = f'{AZURE_ACCOUNT_NAME}.blob.core.windows'
STATIC_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{STATIC_LOCATION}/'

print("Hello")
#print (STATIC_URL)

MEDIA_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{MEDIA_LOCATION}/'

print(MEDIA_URL)

MAINTENANCE_MODE = None
