Cannot read property 'ext' of null

Describe the bug

I'm trying to generate Python code from the repo https://bitbucket.org/qbmt/zbos-mqtt-api/src/master/ .
When I'm running ag master/zbos_mqtt-all-asyncapi.json @asyncapi/python-paho-template -o python I'm getting the following error:

Something went wrong: Template render error: (/usr/local/lib/node_modules/@asyncapi/generator/node_modules/@asyncapi/python-paho-template/template/main.py) [Line 25, Column 27] TypeError: Cannot read property 'ext' of null at Object._prettifyError (/usr/local/lib/node_modules/@asyncapi/generator/node_modules/nunjucks/src/lib.js:36:11) at /usr/local/lib/node_modules/@asyncapi/generator/node_modules/nunjucks/src/environment.js:563:19 at Template.root [as rootRenderFunc] (eval at _compile (/usr/local/lib/node_modules/@asyncapi/generator/node_modules/nunjucks/src/environment.js:633:18), <anonymous>:305:3) at Template.render (/usr/local/lib/node_modules/@asyncapi/generator/node_modules/nunjucks/src/environment.js:552:10) at Environment.renderString (/usr/local/lib/node_modules/@asyncapi/generator/node_modules/nunjucks/src/environment.js:380:17) at /usr/local/lib/node_modules/@asyncapi/generator/lib/renderer/nunjucks.js:32:14 at new Promise (<anonymous>) at nunjucksExport.renderNunjucks (/usr/local/lib/node_modules/@asyncapi/generator/lib/renderer/nunjucks.js:31:10) at Generator.renderFile (/usr/local/lib/node_modules/@asyncapi/generator/lib/generator.js:703:12) at Generator.renderAndWriteToFile (/usr/local/lib/node_modules/@asyncapi/generator/lib/generator.js:617:27) at Generator.generateFile (/usr/local/lib/node_modules/@asyncapi/generator/lib/generator.js:667:5) at Generator.filesGenerationHandler (/usr/local/lib/node_modules/@asyncapi/generator/lib/generator.js:542:7) at Walker.<anonymous> (/usr/local/lib/node_modules/@asyncapi/generator/lib/generator.js:466:11)

The generation of markdown (@asyncapi/markdown-template) is working so there seems to be a problem with the Python generator.

How to Reproduce

git clone https://bitbucket.org/qbmt/zbos-mqtt-api/src/master/
ag master/zbos_mqtt-all-asyncapi.json @asyncapi/python-paho-template -o python

Expected behavior

The Python code should be generated.
