Hi community,

I had a scenario using Parse CSV module that was working properly (scenario is not activated yet, and ran on demand)

Unexpectedely, while no changes have been made, I now get a BundleValidationError  
I ve restored the most recent version of the scenario (that also used to work properly on demand), but still get the error

Again, no changes have been made

Any idea ?

Screenshot of the scenario (quite simple) :

Update: actually the issue appears when I choose to activate the scenario. What makes the buffer error arise in that case ? Anyone knows what to do to fix this ? thank you!

Wrap the Data variable in a `toString` function.

Hope this helps! Let me know if there are any further questions or issues.
