Hey guys, when trying to create an API context with the latest version of the python package, I get the error in issue title.

The following is the full traceback with the API key removed:

@craig-matadeen thanks for building on the Python SDk. I tried to recreate your issue but I don't run into that error. In the hackathon we held last week, we saw some people not having the imports correct. Just to make sure you're creating the context properly I have this snippet for you as example:

from bunq.sdk.context.api_context import ApiContext, ApiEnvironmentType
from bunq.sdk.context.bunq_context import BunqContext


BUNQ_USER_API_KEY = "YOUR_API_KEY"

api_context = ApiContext.create(
    ApiEnvironmentType.SANDBOX,
    BUNQ_USER_API_KEY,
    "name of your project"
)

BunqContext.load_api_context(api_context)
user_context = BunqContext.user_context()


print(user_context.user_id)

Does this snippet work for you? I also see you set ApiEnvironmentType.PRODUCTION to production, is that intentional? If yes: does the error also show on sandbox? I checked both Sandbox and Production and the code below works for creating the context.

[craig-matadeen]

Hey @two-trick-pony-NL, I'm getting the same error with the snippet you provided. This is under a new python 3.12.9 environment (via conda) with the bunq-sdk installed.

Using production is intentional as I'm trying to programmatically access my transactions. It's unfortunate that Bunq doesn't have read only API keys.

I tried logging into the developer portal to create a sandbox key to test the code snippet you provided with Sandbox, but it keeps saying "Whoops! You're using the bunq app faster than expected. For your security, let's pause for a coffee break and try again shortly." even after waiting and retrying later on.

[two-trick-pony-NL]

@craig-matadeen Thanks!

For the future You can grab a sandbox API key here:

curl --location --request POST 'https://public-api.sandbox.bunq.com/v1/sandbox-user-person' \
--header 'Content-Type: application/json' \
--header 'User-Agent: postman' \
--data ''

You can fund that user account with some payments by following our tutorial: https://doc.bunq.com/tutorials/your-first-payment/setting-up-a-sandbox-user

I suspect an issue with Conda, I'll have time to test that later today. In case you're quicker than me: feel free to try the 'standard' environment and pip as well.

[craig-matadeen]

@two-trick-pony-NL Thanks for the quick response. It's strange that conda should be the issue but I'll test it out during the day. By the way, what version of python are you using? I saw on the pypi page that the package requires python>=3.7 but under the programming language section it specifies Python 3.7.

[two-trick-pony-NL]

@craig-matadeen I'm on 3.13.1 but must say: we just had our hackathon and python version issues were not reported. So I suspect conda. If not: I'll have to dig a bit deeper

[craig-matadeen]

@two-trick-pony-NL Hey mate, I tested the snippet you provided using a sandbox key and it works fine, so it's unlikely to be related to conda I think.

With regards to production, the API key is the key that results in the issue is generated from the android application (Settings > API Keys)? Are those keys supposed to be prepended with anything similar to how the sandbox keys are prepended with sandbox_?

I did make raw queries yesterday with the API directly without using the python-sdk and the key that I generated from the android application worked for production. I started working with the raw API yesterday since the python-sdk for production wasn't working but I would prefer not to continue with that route since it's more involved.

I'll clone the repository and do some step through the code and try to figure out why the issue happens.

[two-trick-pony-NL]

Ok let us know! Else I'll add your findings to our internal bug report 👍🏻
To answer your question: No API keys in production are not prepended - they usually also show another error message

I edited the converter.py module to try and debug the _deserialize_dict method with the following changes:

	@classmethod
	def _deserialize_dict(cls,
						  cls_target: Type[T],
						  dict_: Dict) -> T:
		instance = None
		dictionary = None
		try:
			instance = cls_target.__new__(cls_target)
			dict_deserialized = cls._deserialize_dict_attributes(cls_target, dict_)
			
			dictionary = cls._fill_default_values(cls_target, dict_deserialized)
		
			instance.__dict__ = cls._fill_default_values(cls_target, dict_deserialized)
		except Exception as error:
			print("cls:", cls)
			print("cls_target:", cls_target)
			print("dict_:", dict_)
			print("Instance Type:", type(instance))
			print("Instance:", instance)
			print("Dictionary:", dictionary)
			print("Exception Type:", type(error))
			print("Error:", error)
			print("\n\n\n\n")
			
			raise error
		

		return instance

I got the following output with the same traceback as before:

I've redacted all the possibly sensitive information. The weird bit for me is that I expected only one set of print statements to be shown before the error is raised and execution stops but in the above, 3 sets of prints were done before the error stopped execution.

I'll continue to have a look but it will take some time as I'll need to understand the underlying code,
