"ERROR: 404: notFound" response to view_signature() function after a name change

[ag14spirit]

Describe the bug
The script exits unexpectedly with "ERROR: 404: notFound - Requested entity was not found."

Expected behavior
In case of an error report back, we would expect a non-critical error to be handled gracefully without a panic exit.
