Dify version

0.15.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I'm using an old version 0.15.3. When I try to call tool which would return file object, the web page crashed.
The message shows "Application error: a client-side exception has occurred (see the browser console for more information).".

I took screenshots of the error message.

The agent app is as follows. The markdown tool would generate a file object. I check the app works on dify cloud, but failed in version 0.15.3 .
I wonder what caused this problem. Are there any simple method to avoid it.

This should be fixed in later versions. Afaik, we do not have a plan to fix it for 0.15.x.

@dosubot[bot] commented on GitHub (May 30, 2025):

The crash you’re seeing when calling a tool that returns a file object in Dify 0.15.3 is caused by a frontend bug: the code tries to call .split('/') on the plugin_id field of a tool collection, but this field can be undefined, null, or an empty string for certain tool types—including file-related tools. When this happens, you get the TypeError: Cannot read properties of undefined (reading 'split') and the web page crashes.

This issue is in the provider-list.tsx file, where the code checks if plugin_id exists but doesn’t ensure it’s a string before calling .split('/'). If the backend omits or nulls plugin_id (which can happen with file tools or custom/workflow tools), the error occurs during rendering and crashes the page. This is a known risk for file object handling and dynamic tool execution scenarios in this version of Dify [source].

To fix this in your current setup, you need to add a type check or input validation before using .split('/') on plugin_id. For example, you can update the relevant code to:

org: typeof collection.plugin_id === 'string' && collection.plugin_id.includes('/') ? collection.plugin_id.split('/')[0] : '',
name: typeof collection.plugin_id === 'string' && collection.plugin_id.includes('/') ? collection.plugin_id.split('/')[1] : collection.name,

This ensures .split() is only called on valid strings containing a /, preventing the crash.

Since you’re self-hosting with Docker, you’ll need to rebuild the frontend after making this change. If you’re not comfortable editing the code, consider upgrading to a newer version of Dify, as this kind of bug may have been addressed in later releases.

If you can share more details about the specific tool or the backend logs when the crash occurs, I can help further pinpoint the issue. No official patches or documentation for this specific bug exist in 0.15.3, so a code fix or upgrade is the best path forward.

@dosu @crazywoola I will take times to upgrade dify. Which script does the bug locate in for 0.15.3 ? I try to edit the code first. It seems there is no code about "split()" in provider-list.tsx for 0.15.3 ?

The bug is in the file web/app/components/tools/provider-list.tsx in Dify 0.15.3. The problematic code is on lines 119 and 120, where .split('/') is called on collection.plugin_id without ensuring it's a string. This can cause a TypeError if plugin_id is undefined or not a string, which matches the error you saw in the browser console. You can see the relevant code here:

org: collection.plugin_id ? collection.plugin_id.split('/')[0] : '',
name: collection.plugin_id ? collection.plugin_id.split('/')[1] : collection.name,

To fix the crash, update these lines to check that plugin_id is a string and contains a / before calling .split('/'):

org: typeof collection.plugin_id === 'string' && collection.plugin_id.includes('/') ? collection.plugin_id.split('/')[0] : '',
name: typeof collection.plugin_id === 'string' && collection.plugin_id.includes('/') ? collection.plugin_id.split('/')[1] : collection.name,

After making this change, rebuild the frontend. If you still can't find the code, make sure you're looking at the correct file and version in your source tree.

@dosu can you switch tag to 0.15.3 first，and then check the bug location again?

I have checked the Dify 0.15.3 codebase and confirmed that the bug is in web/app/components/tools/provider-list.tsx on lines 119 and 120. The code calls .split('/') on collection.plugin_id without verifying it is a string, which can cause the TypeError you saw:

org: collection.plugin_id ? collection.plugin_id.split('/')[0] : '',
name: collection.plugin_id ? collection.plugin_id.split('/')[1] : collection.name,

To fix this, update those lines to:

org: typeof collection.plugin_id === 'string' && collection.plugin_id.includes('/') ? collection.plugin_id.split('/')[0] : '',
name: typeof collection.plugin_id === 'string' && collection.plugin_id.includes('/') ? collection.plugin_id.split('/')[1] : collection.name,

If you cannot find this code, make sure you have checked out the correct tag. You can do this with:

git fetch --all --tags
git checkout tags/v0.15.3

Then look for provider-list.tsx in web/app/components/tools/. After editing, rebuild the frontend to apply the fix.

This matches the upstream 0.15.3 code and the bug is confirmed in that location. If you still can't find it, there may be a discrepancy in your local files—let me know if you need help verifying your setup.
