TypeScript error: Void is not assignable to parameter type
I am getting this error in TypeScript:
Argument type (response: Response<DSBMannschaftDTO>) => void is not
assignable to parameter type ((value:Response<DSBMannschaftDTO>) =>
(PromiseLike<void> | void)) null | undefined | undefined
This is my schema:
export class DsbMannschaftDTO implements DataTransferObject {
id: number;
vereinId: number;
nummer: number;
benutzerId: number;
veranstaltungsId: number;
version: number;
static copyFrom(optional: {
id?: number,
vereinId?: number,
nummer?: number,
benutzerId?: number;
veranstaltungsId: number;
version?: number
} = {}): DsbMannschaftDTO {
const copy = new DsbMannschaftDTO();
copy.id = optional.id || null;
copy.vereinId = optional.vereinId || null;
copy.benutzerId = optional.benutzerId || null;
copy.veranstaltungsId = optional.veranstaltungsId || null;
copy.nummer = optional.nummer || null;
copy.version = optional.version || null;
return copy;
}
}
and this is my code
private loadTableRows() {
this.loading = true;
this.dsbMannschaftDataProvider.findAll()
.then(onfulfilled:(response: Response<DsbMannschaftDTO>) => this.handleLoadTableRowsSuccess(response))
.catch(onrejected:(response: Response<DsbMannschaftDTO>) => this.handleLoadTableRowsFailure(response));
}
What exactly does this error mean? Thank you very much in advance

It looks like you tried to satisfy a promise value with a method that returns void, and typescript is telling you that you can't do that.

The problem here is your object definition. You defined DsbMannschaftDTO like:
id: number; <- value has to be a number
vereinId: number; <- value has to be a number
and so on. Now you pass the options object with the definition:
id?: number, <- number or undefined
vereinId?: number, <- number or undefined
this is the first missmatch to number. number | undefined is not assignable to number.
And then you write:
copy.id = optional.id || null; <- copy.id can now be number or undefined or null.
This is the second missmatch to number. number | undefined | null is not assignable to number.
To fix this, replace the null with 0 (better to say with a type matching default).
