title: Error while fetching enum value from database: No enum constant, nested exception is java.lang.IllegalArgumentException
body: <p>I was trying to build a sample application in which user can add a post and others can upvote or downvote it. I have taken Vote as an entity class which saves the data whether the user has upvoted or downvoted. upvote and downvote are represented as an enum. When I was trying to fetch all votes by a post id and user id then I am getting an error as  <code>No enum constant com.sachinmukherjee.model.VoteType.up; nested exception is java.lang.IllegalArgumentException: at java.lang.Enum.valueOf()</code></p>
  <p>My Vote Class <strong>(Vote.java)</strong> looks like this</p>
  <pre><code>package com.sachinmukherjee.model;
  @Data
  @NoArgsConstructor
  @AllArgsConstructor
  @Entity
  public class Vote {
      @Id
      @GeneratedValue(strategy = GenerationType.IDENTITY)
      private long id;
      @Enumerated(EnumType.STRING)
      @Column(length = 4)
      private VoteType voteType;
      @ManyToOne(fetch = FetchType.EAGER)
      @JoinColumn(name = &quot;post_id&quot;, referencedColumnName = &quot;id&quot;)
      private Post post;
      @ManyToOne(fetch = FetchType.LAZY)
      @JoinColumn(name = &quot;user_id&quot;, referencedColumnName = &quot;id&quot;)
      private User user;
  }
  </code></pre>
  <p>My VoteType <strong>(VoteType.java)</strong> enum class looks like this</p>
  <pre><code>package com.sachinmukherjee.model;

              this.direction = direction;
      }
      
      public String getDirection() {
          return direction;
      }
      
      public static VoteType getVoteType(String direction) {
          switch (direction) {
          case &quot;up&quot;:

  <p>My VoteRepository <strong>(VoteRepository.java)</strong> class looks like this</p>
