Type '{ start: number; width: number; commonName: string; occurrence: number; kind: string; }[]' is not assignable to type 'BarDataType[]'.

Property 'ownerSVGElement' does not exist on type 'EventTarget'.

Object is possibly 'undefined'.

Conversion of type '{ name: string; entryType: string; startTime: number; duration: number; operations: { "ticket/activation": { kind: string; metadata: { origin: string; ticketId: string; }; operationId: string; operationName: string; tasks: ({ ...; } | ... 13 more ... | { ...; })[]; includedCommonTaskNames: string[]; }; }; }' to type 'Operation' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
