Merge #19632: test: Catch decimal.InvalidOperation from TestNodeCLI#send_cli

82fc4017b7 test: Catch decimal.InvalidOperation from TestNodeCLI#send_cli (Ben Woosley)

Pull request description:

  `decimal.InvalidOperation` is a special case of a float parsing error, which
  presumably should be handled in the same way as a general parsing error,
  rather than blow up.

  Alternatives include: logging the error, or re-raising with more information.

  Example log output:
  ```
