Any solution to this? Or a workaround without having to change params?

I recently solved this particular issue. You need a minimum of 28 sets of ticker features (open, high, low, close, volume) in order to properly calculate all of the TA features that are derived from the add_all_ta_features function, otherwise you'll get this error (and others if you go even lower). It's not shown anywhere in the documentation but I got this bug when adding fewer than 28 sets but it went away at 28 and higher. Hope that helps, this was driving me nuts.

Wow thanks @legionnaire12. I might check this out and see if I can get it to work with your workaround. I put this project on hold due to this issue months ago.

Confirming @legionnaire12 's comment. You need to have more than 28 rows in your dataframe to proceed.
