05/16/2025, 5:26 AMHi Team,
I tried the latest Version 0.1623.0 - Lightdash, Tested yesterday if the scheduled Deliveries were initiated correctly and Are we even able to view the data after downloading the ".csv" File and yes I was able to see the data as well. Today I was planning to test the "image and Attach a PDF" option But on logging in to the Dashboard I could see a new Error as mentioned below which is not allowing me to even view the Saved chart :

Geethika S Gireesh
05/16/2025, 7:19 AMIs there something that I"ll need to enable which will help in image deliveries. The error message is as mentioned below :

05/16/2025, 7:54 AMOn further testing I am again receiving the Error :
Failed to send scheduled delivery
char 'n' is not expected.11 Deserialization error: to see the raw response, inspect the hidden field {error}.$response on this object.
on trying to send image using scheduled deliveries.
Will this be related to resource limits ?

Geethika S Gireesh
05/16/2025, 8:32 AMWhen we login to lightdash dashboard, this error pops up suddenly, during that time we are not able to create or save charts, Send chart.
After sometime this error goes away and then suddenly the saved chart starts to diplay.

> One thing I haven't done is that I havent wiped out the sample SEED_SCHEMA Data this had previously, should I wipe that out from the database and re initiate the "lightdash dbt run" command for this to function correctly ?
Geethika S Gireesh
05/16/2025, 9:40 AMok I wiped out DB data , re initialized the dbt commands and I still get the below error after chart is saved :
char 'u' is not expected.11 Deserialization error: to see the raw response, inspect the hidden field {error}.$response on this object.

This error pops up when we try to send schedule deliveries selecting the "image and pdf" Option via the lightdash dashboard.

05/20/2025, 8:24 AMHi @Geethika S Gireesh, I see. Before we proceed, can you confirm that you are running the latest version of Lightdash? Also, can you confirm that you’ve configured S3 according to the announcement? https://lightdash-community.slack.com/archives/C039GAKTPMK/p1747056127610149

Once I installed that I was able to view the .csv data sent via scheduled deliveries.
