Fabric Trial: PermissionDeniedError 403 when testing Copilot with pandas AI functions

azaterol — Thu, 28 Aug 2025 10:16:13 GMT

I started the Microsoft Fabric trial and also created a Fabric trial workspace. The workspace capacity region is set to Germany West Central.

I am following along with a YouTube tutorial and inserted 3 blocks of code:

1.)

# The pandas AI functions package requires OpenAI version 1.30 or later.
%pip install -q --force-reinstall openai==1.30 2>/dev/null

# AI functions are preinstalled on the Fabric PySpark runtime.

2.)

import pandas as pd
# Load data into pandas DataFrame from "/lakehouse/default/Files/MovieInfo.csv"
df = pd.read_csv("/lakehouse/default/Files/MovieInfo.csv").head(20)
display(df)

3.)

df["A"] = df["content"].ai.translate("german") 
display(df)

I get the following error:

PermissionDeniedError: Error code: 403 - {'Message': 'FTL64 SKU Not Supported', 'Source': 'OPENAI', 'error_code': 'PERMISSION_DENIED'}

What is the issue?
I want to test Copilot together with Fabric.

What else do I need to activate to get this running?
I already enabled all tenant settings for Copilot and Fabric.

I hope someone can help me.

Hello azaterol,

The Fabric Trial SKU (FTL64) gives you temporary access to explore core Fabric workloads (Lakehouse, Warehouse, Data Engineering, etc.).
However, Copilot and AI functions require a paid Fabric capacity (F SKUs like F2, F4, F64, etc.).
On the free trial SKU, any call to AI features will return 403 Permission Denied.

What you need

Move your workspace to a paid Fabric capacity (for example F2 or higher).
AI-powered features (Copilot in Notebooks, pandas AI functions, AI skills) only light up on paid SKUs, not on the free trial.

You can test on the smallest SKU, F2, it’s relatively inexpensive.

See the prerequisites in the source : https://learn.microsoft.com/en-us/fabric/data-science/ai-functions/overview?tabs=pandas-pyspark%2Cpandas#prerequisites

Hope it can help you !

Best regards,

Antoine
