# Description Fixes: #11351 And comment here is also fixed: https://github.com/nushell/nushell/issues/11351#issuecomment-1996191537 The panic can happened if we pipe a variable to a custom command which recursively called itself inside another block. TBH, I think I figure out how it works to panic, but I'm not sure if there is a potention issue if nushell don't mutate a block in such case. # User-Facing Changes Nan # Tests + Formatting Done # After Submitting Done --------- Co-authored-by: Stefan Holderbach <sholderbach@users.noreply.github.com>
