Warning: Failed prop type: Invalid prop `actions[0]` supplied to `MaterialTable`.

This error shows up in the console. I have tried to remove each singular line inside of the ‘actions’ but the error only goes away if I remove ‘actions’ itself or everything inside.

This is my ‘actions’ code: actions={[ { icon: Print, tooltip: 'Print', onClick: (event, rowData) => { this.setState({ rowData }) this.handleClickOpen() }, } ]}

Try this

icon: () => <Edit/>

I am having same error in Material Table using this

actions={[
                  {
                    icon: "add",
                    isFreeAction: true,
                    onClick: undefined
                  }
                ]}
                components={{
                  Action: props => <NewBin refetch={this.requireRefetch} />
                }}

and this

actions={[
                  {
                    icon: () => <NewBin refetch={this.requireRefetch} />,
                    isFreeAction: true,
                    onClick: undefined
                  }
                ]}

Issued solved. If any one get this error you can try this

actions={[
                  {
                    icon: "add",
                    isFreeAction: true,
                    onClick: () => {}
                  }
                ]}
                components={{
                  Action: props => <NewBin refetch={this.requireRefetch} />
                }}
