current_data = process_datajoincurrent_dataTypeError sequence item 0 expected str instance bytes found

The error is occurring because the current_data variable is a list of bytes, but the process_data function expects a string as input.

To fix this, you can convert the bytes to a string before passing it to the process_data function. You can use the decode() method to convert the bytes to a string, specifying the appropriate encoding.

Here's an example of how you can modify the code:

current_data = []
data_string = ''.join(current_data).decode('utf-8')
process_data(data_string)

Replace 'utf-8' with the appropriate encoding if your data is encoded differently.
