YAML MismatchedInputException: Cannot deserialize instance of java.lang.String when passing file path as String

[serpro69]

I have a yaml file that I want to read into Map<String, String>:

    events:
      key1: val1
      key2: val2
      key3: val3

This piece of code is working fine.

public class EventGenerator {    
     private Map<String, String> events;
   
     public Map<String, String> getEvents() {
       return this.events;
     }
   
     public void setEvents() {
       ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
           try {
               FileInputStream fis = new FileInputStream("file.yaml");
               EventGenerator eventGenerator = mapper.readValue(fis, EventGenerator.class);
               fis.close();
               System.out.print(eventGenerator.getEvents());
           } catch (IOException e) {
               e.printStackTrace();
           }
   
     }
   
   }

But when I pass path of yaml file as a String (and/or File) argument

    public void setEvents(String filePath) {
    // same code
    FileInputStream fis = new FileInputStream(filePath)
    // same code
    }

I'm getting an exception

jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of java.lang.String

Also, when I override the setEvents() method and have both setEvents() and setEvents(String filePath) then neither are working and both are giving the above exception.

UPD (sorry, forgot to add pom)
jackson pom dependencies:

        <dependency>
            <groupId>com.fasterxml.jackson.dataformat</groupId>
            <artifactId>jackson-dataformat-yaml</artifactId>
