TS2590: Expression produces a union type that is too complex to represent
🕗 Version & Regression Information
- This changed between versions 4.9.4 and 5.0.0-dev.20230125
💻 Code
Simplified Version
import { Button } from "@chakra-ui/react"
export const CustomButtonCell = (): JSX.Element => {
return (
<Button
gap={3}
p={4}
h={"initial"}
textAlign={"left"}
fontWeight={"initial"}
rounded={"xl"}
/>
)
}
Actual Version
import { Button } from "@chakra-ui/react"
import { ComponentProps } from "react"
export interface CustomButtonCellProps extends ComponentProps<typeof Button> {
highlighted?: boolean
transparent?: boolean
}
export const CustomButtonCell = ({
highlighted,
transparent,
...rest
}: CustomButtonCellProps): JSX.Element => {
const colorScheme = transparent
? "transparent"
: highlighted
? "tertiary"
: "neutrals"
return (
<Button
gap={3}
p={4}
h={"initial"}
textAlign={"left"}
fontWeight={"initial"}
colorScheme={colorScheme}
rounded={"xl"}
{...rest}
/>
)
}
🙁 Actual behavior
On both of the versions, typescript throws similar error:
ERROR in ./src/ui/components/CustomButtonCell.tsx:4:18
TS2590: Expression produces a union type that is too complex to represent.
2 | import { ComponentProps } from "react"
3 |
> 4 | export interface CustomButtonCellProps extends ComponentProps<typeof Button> {
| ^^^^^^^^^^^^^^^^^^^^^
5 | highlighted?: boolean
6 | transparent?: boolean
7 | }
🙂 Expected behavior
This is a very simple JSX.Element. It worked fine with typescript 4.9.4 but our project needed the latest moduleResolution: "bundler" support for some of the dependencies.
External Dependencies
"@chakra-ui/react": 2.9.4 - also tried 2.7.4
