General::noinfo

Details

This message is generated by an attempt to make an expression from a TagBox in which the second argument is False.
Some Wolfram Language functions, such as InterpolatingFunction and SparseArray, produce expressions of this form to save space in notebooks. These functions typically style their names in gray.
This message can also occur if improperly constructed typeset input is evaluated.
Off[message] switches off the message; On[message] switches it on. For example: Off[General::noinfo].

Copying the output and using it as input without clicking "Store now" will fail:

Instead, store the SparseArray in a variable and refer to it by name:
