error[E0277]: `?` couldn't convert the error to `ApplicationError`

LL | t.run()?;
|
|
| -----^ the trait `From<<T as Trait>::Error>` is not implemented for `ApplicationError`
|
|
| |
|
|
| this can't be annotated with `?` because it has type `Result<_, <T as Trait>::Error>`
|
|
|
|

note: `ApplicationError` needs to implement `From<<T as Trait>::Error>`

|
| ^^^^^^^^^^^^^^^^^^^^^
|
|
= note: the question mark operation (`?`) implicitly performs a conversion on the error value using the `From` trait
|
|
help: consider introducing a `where` clause, but there might be an alternative better way to express this requirement
|
