TA_EMA function failed with error code 2: Bad Parameter (TA_BAD_PARAM) #502

I calculate value_ by giving value to the length, but when I give the 1, I get the error in the title

df[value_]=ta.EMA(df , length)

There is no problem when I give a value greater than 2

Sorry for the late response. If you continue to give the Length value as 1, you will continue to receive an error. However, using df['close'] instead of trying to give the Length value as 1 will solve the problem. The EMA1 value will already be equal to the last closing price.

I don't think you want to pass length, you want to pass the period for the EMA calculation, and you probably don't just want the defaults to 30, I think.
