microdot utemplate in asyncio

[Gingso]

Hey,

i tried to use utemplate with microdot on my esp32, with the latest OTA Firmware. But I'm not able to get it running :-/ (microdot itself is running for standard requests)

What i did so far:

• include the Libs for microdot asyncio and utemplate via Thonny on my esp32
• create a folder "templates" which include a "index.html" with some {{ variables }} attributes

implement the following code:

import uasyncio as asyncio
from microdot_asyncio import Microdot, Response
from microdot_utemplate import render_template

app = Microdot()
Response.default_content_type = 'text/html'

..........

@app.route('/')
async def mainpage(request):
    name='myname'
    return render_template(template='index.html', location=name)

When I connect to the webserver it crashes:

Traceback (most recent call last):
  File "/lib/microdot_asyncio.py", line 367, in dispatch_request
  File "/lib/microdot_asyncio.py", line 423, in _invoke_handler
  File "<stdin>", line 130, in mainpage
  File "/lib/microdot_utemplate.py", line 34, in render_template
TypeError: unexpected keyword argument 'location'

what i figured out so far:

• in templates an index_html.py file is generated
  --> If i copy paste the included render function to my code and execute directly, everything works fine.

• It looks like an issue with the loader / Load function in microdot_utemplate.py:

    if _loader is None:  # pragma: no cover
        init_templates()
    render = _loader.load(template)
    return render(*args, **kwargs)

any ideas how to fix this?

I do not know how this loader construct work, but it seems to me that it has to be "render.render(*args, **kwargs)" to execute the render function in the .py file....

issue can be closed, i had a typo in the template (special character which was overlooked)
