I found two similar discussions that might be relevant to your issue:

  1. (bug)dify cloud Version 0.6.12-fix1 版本工作流中的代码执行单元无法正常使用requests which was last updated on 2024-08-03.
  2. Sandbox import error: ModuleNotFoundError: No module named 'requests' error: exit status 255 which was last updated on 2024-06-04.

The issue you're encountering with the requests module in the sandbox environment is due to missing character detection dependencies (chardet or charset_normalizer). These dependencies are not listed in the pyproject.toml file under the [tool.poetry.dependencies] section. To resolve this, you need to add either chardet or charset_normalizer to the dependencies in the pyproject.toml file. Here is how you can do it:

[tool.poetry.dependencies]
# existing dependencies
chardet = "~5.1.0"  # Add this line to include chardet
# or
charset_normalizer = "~3.2.0"  # Add this line to include charset_normalizer

Make sure to add only one of these dependencies, as requests can use either for character encoding detection [1].

Additionally, there are known limitations regarding the use of external libraries like requests in the sandbox environment. The sandboxed execution environment restricts making network requests to ensure security [2].

To continue talking to Dosu, mention @dosu.

Could this issue be related to the removal of “Advanced Dependencies” from the panel?

Yes, the issue could be related to the removal of “Advanced Dependencies” from the panel. The AdvancedSetting component, which is part of the panel, includes various advanced settings such as memory settings, instruction changes, and other configurations. If this component or its dependencies were removed, it could potentially cause issues in the functionality of the panel.

Here is the relevant part of the code that includes the AdvancedSetting component:

<Field
  title={t(`${i18nPrefix}.advancedSetting`)}
  supportFold
>
  <AdvancedSetting
    hideMemorySetting={!isChatMode}
    instruction={inputs.instruction}
    onInstructionChange={handleInstructionChange}
    memory={inputs.memory}
    onMemoryChange={handleMemoryChange}
    readonly={readOnly}
    isChatApp={isChatMode}
    isChatModel={isChatModel}
    hasSetBlockStatus={hasSetBlockStatus}
    nodesOutputVars={availableVars}
    availableNodes={availableNodesWithParent}
  />
</Field>

If the AdvancedSetting component or its dependencies were removed, it could lead to issues in the panel's functionality [1].

And the pic below shows the site-packages of sandbox v0.2.6 in /usr/local/lib/python3.10/site-packages

image

It does contain requests and charset_normalizer, but I have no idea why it fails

FYI, In 0.2.6, we no longer need to include it in advance settings. I think you can try httpx.
