Missing validations

[Jorricks]

Recently I noticed that I used a Header and it had more then a 150 characters. In that case, you get back quite a cryptic message from Slack making it hard to debug if you don't know the exact payload.
I was wondering if we were already doing content validation like this upon build. I don't mind adding the validations.
Things that come to mind:

• Tables have a max of 20 columns and 100 rows
• Headers have a max length of 150

Hey @Jorricks! Looks like the Header validations are working fine. I couldn’t reproduce the issue on my end. The library already handles most of the validation, but Table size checks are planned for the next release.

Could you share a bit more detail or an example where the Header validation fails? That’ll help me reproduce it and dig in further.
