Are all NLU nodes supported in LLM for Virtual Agent?

[MayrelCerero]

We used the migration tool to transfer our NLU topics and topic blocks, but I am encountering loops or virtual agent conversations ending with a specific topic block. Does this indicate that some NLU nodes converted to LLM nodes are not supported? For instance, I have a dynamic choice input (refer to the screenshot) that was converted, but I am unable to determine the cause of the issues. The script under the NLU topic previously used gs.log, which I changed to gs.info, making me question if this node is unsupported. The script in this node is for a REST API call that allows users to reset their passwords.
