Code node throws "Cannot read properties of undefined (reading 'text')" in version 1.75.2

[Mario_Nogueira]

Describe the problem/error/question

I have a SQL agent connected to a MySQL database. Before the latest version (1.75.2) this worked fine. Now I get the error
“Cannot read properties of undefined (reading ‘text’)” in my code node.
Was there a problem in version 1.75.2?

What is the error message (if any)?

Cannot read properties of undefined (reading ‘text’)

hi all

Took a quick look internally and couldn’t find any similar issues opened, are you both using local setups? mind trying this on cloud just to exclude local setups?

Thanks!

Actually, I think it’s the model. i switched to gemini-flash-1.5 from google/gemini-2.0-flash-exp:free and don’t get the issue any longer.
