Check Existing Issues

I have searched the existing issues and discussions.
I am using the latest version of Open WebUI.

Installation Method

Git Clone

Open WebUI Version

v0.6.15

Ollama Version (if applicable)

No response

Operating System

macOS

Browser (if applicable)

Chrome

Confirmation

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

When asking model to generate pdf file with code interpretor, when executing resuslt in error (Pyodide enabled)

model: gpt-4.1
query: "generate pdf file with random username rows to"

Actual Behavior

output: Certainly! Here’s sample Python code to generate a simple “Guide” PDF using ReportLab. You can copy, tweak, and run this on your machine to create the guide.
`
from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer, Table, TableStyle
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib import colors

Create the PDF document

doc = SimpleDocTemplate("sample_guide.pdf", pagesize=letter)
styles = getSampleStyleSheet()
elements = []

Title

elements.append(Paragraph("Quick Guide to Using Your PDF", styles['Title']))
elements.append(Spacer(1, 24))

Introduction Paragraph

intro = ("This guide provides quick instructions on how to use your newly generated PDF document. "
"You will learn to view, print, and share this file.")
elements.append(Paragraph(intro, styles['Normal']))
elements.append(Spacer(1, 18))

Table Example

table_data = [
['Step', 'Description'],
['1', 'Download the PDF file to your device.'],
['2', 'Open the PDF using any PDF reader (such as Adobe Reader or your browser).'],
['3', 'Review the content and print if necessary.'],
['4', 'Share the PDF via email or other means if required.']
]
table = Table(table_data, hAlign='LEFT')
table.setStyle(TableStyle([
('BACKGROUND', (0,0), (-1,0), colors.HexColor('#dbeafe')),
('TEXTCOLOR',(0,0),(-1,0),colors.HexColor('#1e3a8a')),
('ALIGN',(0,0),(-1,-1),'LEFT'),
('GRID', (0,0), (-1,-1), 1, colors.grey),
('FONTNAME', (0,0), (-1,0), 'Helvetica-Bold'),
]))
elements.append(table)
elements.append(Spacer(1, 18))

Tips Section

elements.append(Paragraph("Tips:", styles['Heading2']))
elements.append(Paragraph(
"- Keep a backup of your PDF.
"
"- Make sure your device has a PDF reader installed.
"
"- For best print quality, use high-resolution settings.",
styles['Normal'])
)

Build the PDF

doc.build(elements)
print("PDF guide 'sample_guide.pdf' created successfully.")
`
on running in chat (Pyodide)

Steps to Reproduce

model: gpt-4.1
query: "generate pdf file with random username rows to"

Logs & Screenshots

STDOUT/STDERR PythonError: Traceback (most recent call last): File "/lib/python312.zip/_pyodide/_base.py", line 597, in eval_code_async await CodeRunner( File "/lib/python312.zip/_pyodide/_base.py", line 411, in run_async coroutine = eval(self.code, globals, locals) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "<exec>", line 1, in <module> ModuleNotFoundError: No module named 'reportlab'

reportlab is not shipped with pyodide, you should use jupyter engine instead.
