Don't display properties panel componente and error gulp bundle --ship TILES-V sample

[andresdperezg]

Best regard,

After several attempts to build and package your SharePoint Framework project into a solution, unfortunately in the step of bundling to combine the different pieces of your Web Part into a single file, gulp bundle --ship does't work, i would like know what is the cause.

It is worth mentioning that I have already carefully reviewed the version of Node.js, npm, Gulp, and SPFx, I also ran the gulp clean command and, last but not least, I tried to infer the error by searching the web but I have not found much information about it.

node version: 10.24.1
npm: 6.14.12
gulp
cli version: 2.3.0
local version: 3.9.1
nvm: 0.39.1

I tried running the gulp bundle --debug command and everything seems to work fine, but when I install the .sppkg package in my SPO tentat it doesn't open the webpart properties panel and checking the console the error seems to be from the spfx-property package -controls. This only happens when the solution is packaged, in Workbench it works correctly, which is exactly what I don't understand.

Attached some images of the error in the VS Code terminal and from the console in Google Chrome.

I hope you can help me please, I will be attentive to any information and in what I can help it would be a pleasure.
