Hi all,
I'm looking to develop a block called dfts ofdm, based in a similar block
called ofdm mod, I change the .xml and .py to a new name called DFTSOFDM,
but I can't make it work. In GRC I have the following error:
Traceback (most recent call last):

Is everything properly in the CMakeLists.txt files? Did you make sure
to rebuild and reinstall? Also, if that doesn't help, rerun cmake on
the project to make sure everything is properly reconfigured.

The new python file es dftsofdm.py, and I change the classes with
class dftsofdm_mod(gr.hier_block2):
class dftsofdm_demod(gr.hier_block2):
The .xml files have this changes:
Umbrella_dftsofdm_demod.xml
<name>DFTSOFDM Demod</name>
<key>Umbrella_dftsofdm_demod</key>
<category>Umbrella</category>
<import>import Umbrella</import>
<import>from grc_gnuradio import blks2 as grc_blks2</import>
<import>from gnuradio import digital</import>
<make>grc_blks2.packet_demod_$(type.fcn)(Umbrella.dftsofdm_demod(
options=grc_blks2.options(
modulation="$modulation",
fft_length=$fft_length,

snr=$snr,

callback=lambda ok, payload: self.$(id).recv_pkt(ok, payload),
