BodyHTML doesn't exist on type Issue

[ycjcl868]

var q struct {
  Repository struct {
    Issue struct {
      Number github.Int `json:"id"`
      Title      github.String `json:"title"`
      URL github.URI `json:"url"`
      CreatedAt  github.DateTime `json:"createdAt"`
      BodyHTML github.String `json:"bodyHTML"`
    } `graphql:"issue(number:31)"`
  } `graphql:"repository(owner: \"\", name: \"\")"`
}

error message: [{%!d(string=Field 'bodyHtml' doesn't exist on type 'Issue') [{1 107}]}]data {{{0 %!d(githubv4.String=) {0} {{0 0 0}} %!d(githubv4.String=)}}}%

but I use https://developer.github.com/v4/explorer/ can output the result:

BodyHTML github.String `json:"bodyHTML"`

You should use "graphql" tag, not "json", to specify the name of the GraphQL field:

BodyHTML github.String `graphql:"bodyHTML"`
