I need to pass the current user name in the filter for Contains condition - Whenever passing [Me] it gives error: Filter value is not a valid text string.
The List View filter value for the people or group field it takes [Me]. It works for Created By in your screenshot. If the PoC field is a text field there is no way you can pass the current user name.
You need to add a "Current User Filter" web part along with list view web part and connect both web parts.
- Go to page where you have list view web part added.
- Add "Current User Filter" web part under "Filters" section in the web parts gallery to the same page.
- Click down arrow on web part and click "connection" and select your list.
- And configure the connection.
