fix: surface initial fields in lists.items.create method arguments by zimeg · Pull Request #1600 · slackapi/java-slack-sdk

zimeg · 2026-06-10T23:27:52Z

Summary

Fix typo in RequestFormBuilder.toForm(SlackListsItemsCreateRequest) where initial_fields was being sent as intial_fields (missing second 'i'), causing list items to be created without their initial field values set.

Fixes #1599

Example

import com.slack.api.Slack;
import com.slack.api.methods.response.slack_lists.SlackListsItemsCreateResponse;
import com.slack.api.model.block.RichTextBlock;
import com.slack.api.model.block.element.RichTextSectionElement;
import com.slack.api.model.list.ListRecord;

import java.util.Arrays;

// ...

ListRecord.Field field = ListRecord.Field.builder()
        .columnId(taskNameColId)
        .richText(Arrays.asList(RichTextBlock.builder()
                .elements(Arrays.asList(RichTextSectionElement.builder()
                        .elements(Arrays.asList(RichTextSectionElement.Text.builder()
                                .text("My new list item")
                                .build()))
                        .build()))
                .build()))
        .build();

// This now correctly sends "initial_fields" instead of "intial_fields"
SlackListsItemsCreateResponse response = slack.methods(token).slackListsItemsCreate(r -> r
        .listId("F1234ABCD")
        .initialFields(Arrays.asList(field)));

+        assertThat(createItemResponse.getItem().getFields(), is(notNullValue()));
+        assertThat(createItemResponse.getItem().getFields().size(), is(1));
+        assertThat(createItemResponse.getItem().getFields().get(0).getColumnId(), is(taskNameColId));
+        assertThat(createItemResponse.getItem().getFields().get(0).getText(), is("Test task item"));


🪬 note: We now confirm the fields used above:

[DEBUG] createItemResponse item=ListRecord(id=Rec0B9VCSAABE, listId=F0B9KD6NECB, fields=[ListRecord.Field(key=task_name, columnId=Col0B9TKAUTND, value=[{"type":"rich_text","block_id":"h2z2t","elements":[{"type":"rich_text_section","elements":[{"type":"text","text":"Test task item"}]}]}], text=Test task item, richText=[RichTextBlock(type=rich_text, elements=[RichTextSectionElement(type=rich_text_section, elements=[RichTextSectionElement.Text(type=text, text=Test task item, style=null)])], blockId=h2z2t)], messages=null, message=null, number=null, select=null, date=null, user=null, attachment=null, checkbox=null, email=null, phone=null, channel=null, rating=null, timestamp=null, link=null, reference=null)], dateCreated=1781134963, createdBy=U09KU686163, threadTs=null, position=null, updatedTimestamp=1781134963, updatedBy=U09KU686163, viewPositions=null, platformRefs=null, isSubscribed=null, saved=null, savedFields=null)

✅ Great catch @zimeg!

mwbrooks · 2026-06-11T01:08:04Z

        if (req.getInitialFields() != null) {
            String json = getJsonWithGsonAnonymInnerClassHandling(req.getInitialFields());
-            form.add("intial_fields", json);
+            form.add("initial_fields", json);


praise: Nice catch 🎉 Silent param-drops are the worst flavour of bug because nothing 4xxs and the request just succeeds with the field missing.
