Please advise?

Hi @tbanov, can you please provide a stack trace including the data being passed to the json_encode method?

Hi @jordyvanderhaegen and thank you for your work

Unfortunately I can't find the passed data in my logs, I have tried to reproduce the issue but with no success for now.

In the man time here is the stack trace:
