So, i need to find in what case there should be an error answer: 400: ENTITIES_TOO_LONG You provided too many styled message entites
I have tg channel and bot added in this channel.
I read telegram API documantation and there is no good explanation of this error.

First of all, i tried to test some cases, for example:

public String generateEntitiesString(int amount) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < amount; i++) {
            sb.append(String.format("[<view merge request\>](%s)", "https://github.com/")+ "n");
        }
        return sb.toString();
    }

I wrote simple code that generates content of the message sended by channel bot. And i found that the max amount of styled text entities is 100. After that all formatted text, such as ~text~ will be ignored. That’s why i don’t understand i will catch 400: ENTITIES_TOO_LONG.
To more information, i send message via class extends DefaultAbsSender like this:

public void sendMessage(String chatId, String content) {
        try {
            sendApiMethod(SendMessage.builder()
                    .parseMode("MarkdownV2")
                    .chatId(chatId)
                    .text(content)
                    .build());
            log.info("Message sended, chatId={}", chatId);
        } catch (TelegramApiException e) {
            log.error("Error, chatId={}, content={}", chatId, content, e);
        }
    }
