Lesson 2 exercise error.

[DaNether]

This error is in the code provide and needs to be corrected or better written to reflect the current systems configuration and instruction for learning. See this link

To replicate: Copy and paste code into workflow and test to see the enclosed screen error Problem in node 'Read/Write files from Disk". I believe I know how to correct yet should be updated in your system for training.

Below is the code from training that has error.

Thanks for the report.

@bartv42 can you take a look at this?

[bartv42]

@DaNether I just ran your code both on our cloud and on a self-hosted system and it works as expected. How do you host? And on which operating system?

[bartv42]

@DaNether Did you see my message above?

[DaNether]

We use cloud and do not host.

Hi @DaNether I'm just circling back to find out if this issue ever got resolved for you
