How can i display information in Info TAB

So I need to create an Onlyoffice DocSpace plugin (and I use ONLYOFFICE to do this operation):
When I select a File into a Room of Docspace I need to see into right pannel of DocSpace (“Informations of File”) a table with fields related to that File (the File has an OlyOffice DocSpace ID, in the below example: fileID is 1527575. The fields al already stored in a Database MySQL and exposed with an API: https://tenca.it/API/apidocspace.php?fileId=1527575 fileId is the ID of that File into Onlyoffice DocSpace Room.

Look at the attached clip or on the youtube link below => The error is happening like this:

I also attached my part from index.ts

class SimplePlugin implements IPlugin, IApiPlugin, IInfoPanelPlugin, IEventListenerPlugin, IFilePlugin {
  status: PluginStatus = PluginStatus.active;
  origin = "";
  proxy = "";
  prefix = "";

  infoPanelItems = new Map<string, IInfoPanelItem>();

  constructor() {
    const key = "info_plugin-File Info";

    const infoPanelItem: IInfoPanelItem = {
      key,
      subMenu: {
        name: "File Info",
        onClick: async (fileId: number) => {
          console.log("✅ onClick called with fileId:", fileId);
          try {
         const fields = [
              ["Corsista", 'Test'],
              ["Cod Fiscal (CF)", 'test'],
              ["Corso",'test'],
              ["Data Corso", 'test'],
              ["Data Scadenza", 'test'],
              ["ID File", 'test'],
              ["ID OnlyOffice", 'test'],
            ];
          console.log(fields)
            const children: Component[] = fields.map(([label, value]) => ({
              component: Components.text,
              props: {
                text: `📌 Test Test`,
                fontSize: "13px",
                lineHeight: "20px",
                noSelect: true,
              } as IText,
            }));

            this.updateInfoPanelItem({
              ...infoPanelItem,
              body: {
                paddingProp: "20px",
                displayProp: "flex",
                flexDirection: "column",
                children,
              },
            });

            return {
              message: `Data for  #${fileId}`,
              type: "info",
            } as IMessage;
          } catch (e) {
            console.log(e)
            return {
              message: "❌ Error.",
              type: "error",
            } as IMessage;
          }
        },
      },
      body: {
        paddingProp: "20px",
        displayProp: "flex",
        flexDirection: "column",
        children: [
          {
            component: Components.text,
            props: {
              text: "🔄 Select a file to view the Mysql Data...",
              fontSize: "13px",
            },
          },
        ],
      },
      onLoad: async () => ({
        body: {
          paddingProp: "20px",
          displayProp: "flex",
          flexDirection: "column",
          children: [

          ],
        },
      }),
      filesType: [FilesType.file],
    };

    this.addInfoPanelItem(infoPanelItem);
  }

  onLoadCallback = async () => {
    console.log("✅ Plugin loaded");
  };

  // === Required methods ===
  addInfoPanelItem = (item: IInfoPanelItem) => this.infoPanelItems.set(item.key, item);
  updateInfoPanelItem = (item: IInfoPanelItem) => this.infoPanelItems.set(item.key, item);
  getInfoPanelItems = () => this.infoPanelItems;
