Error when animating Pcolormesh plots

Hello, I receive the following error, when I try to animate 12 Pcolormesh plots using ct.animate.figure:

Traceback (most recent call last):
File "/opt/cdstoolbox/cdscompute/cdscompute/cdshandlers/services/handler.py", line 49, in handle_request

context.run_command('/bin/bash', '-c', '%s' % " ".join(cmd + palette_opt))
TypeError: sequence item 1: expected str instance, dict found

I use the following code:

figs = []
for mm in range(1,13):
month = '%02d'%(mm)
data = ct.catalogue.retrieve(
'satellite-humidity-profiles', {
'year':Year,
'month':month,
'variable': 'all',
'product_type': Product_type.lower().replace(' ','_'),
'product_version': '0010',
}
)
print(data)
if mm==1:
year_data = data
else:
year_data = ct.cube.concat([year_data,data], dim='time')

fig = ct.cdsplot.figure(suptitle='Zonal Humidity - '+Year+month)
fig = ct.cdsplot.pcolormesh(
data, cmap='coolwarm', x='lat', y='height',
ylim=[0,1.2e4], fig=fig)

figs.append(fig)
anim = ct.animate.figure(figs)

The rest of the code can be found here:

I hope someone can help.

Thank You.
