@ChenZhongPu Hello there! I'm here to help you with any bugs, questions, or contributions you have for the Dify repository. Let me know how I can assist you!
To resolve the "'NoneType' object is not iterable" error when adding DALL-E in the tool tab of a self-hosted Dify version 0.7 using Docker, ensure that the credentials
dictionary passed to the _validate_credentials
method is not None
and contains the necessary keys and values.
Here's the relevant code snippet from dalle.py
:
class DALLEProvider(BuiltinToolProviderController):
def _validate_credentials(self, credentials: dict[str, Any]) -> None:
try:
DallE2Tool().fork_tool_runtime(
runtime={
"credentials": credentials,
}
).invoke(
user_id='',
tool_parameters={
"prompt": "cute girl, blue eyes, white hair, anime style",
"size": "small",
"n": 1
},
)
except Exception as e:
raise ToolProviderCredentialValidationError(str(e))
Make sure that when you are adding DALL-E, the credentials
dictionary is properly populated. For example:
credentials = {
"api_key": "your_api_key_here",
"other_required_field": "value"
}
If credentials
is None
or missing required fields, the fork_tool_runtime
method will fail, leading to the "'NoneType' object is not iterable" error. Ensure that the credentials
dictionary is correctly passed and contains all necessary information [1].
Additionally, the required field in the credentials
dictionary for the DALL-E tool is openai_api_key
:
credentials_for_provider:
openai_api_key:
type: secret-input
required: true
label:
en_US: OpenAI API key
zh_Hans: OpenAI API key
pt_BR: OpenAI API key
help:
en_US: Please input your OpenAI API key
zh_Hans: 请输入你的 OpenAI API key
pt_BR: Please input your OpenAI API key
placeholder:
en_US: Please input your OpenAI API key
zh_Hans: 请输入你的 OpenAI API key
pt_BR: Please input your OpenAI API key
Ensure that you provide the openai_api_key
in the credentials [2].

Steps to reproduce
Dify is self-hosted using Docker in a Linux machine without public IP, so I used port forwarding techs to access it with a customized domain.
The chatbot works fine with a proxy OpenAI API endpoint, but it reports 'NoneType' object is not iterable while adding DALL-E in
tool
tab. I also checked the web console:where
xxx.com
is my domain.✔️ Expected Behavior
No response
