Python Script Error : The preview for Section1/Query1/Source doesn't exist
Hi Team,
For my dashboard I am using Python script for data extraction and performing some ETL opearation to fine tune the data.
My dataframe declaration is quite similar to the below dataframe.
import pandas as pd
data = [['Alex',10],['Bob',12],['Clarke',13]]
df = pd.DataFrame(data,columns=['Name','Age'],dtype=float)
I have set the path of Python home directory in the settings part of PowerBI desktop as shown below.
Python Directory:
Error:
If I am executing the script outside of Power BI desktop then the script is working fine and it's producing the desired output.
But when I am executing the same script from Power BI desktop then it's throwing the below error.
I am not able to proceed further from last 1.5 days , kidly help me in fixing this issue.

Hey!
I just stumbled upon this while trying to troubleshoot the same thing.
When I was receiving this error, it was trying to report a ~650x12 matrix. I scaled back the reporting manually and tried with a single row, and that worked!
The nature of the project I'm working on is to get ADO Work Item data reporting, so I just needed to narrow down the query of work items.
All that to say, try and scale down the number of rows, and see if it works, and then continue to test the bounds.
Hope this helps
