TypeError: dropzone__WEBPACK_IMPORTED_MODULE_1__ is not a constructor

[Cristhianzl]

Hello,

All the dropzones that I'm using in my project stoped working from nothing.
I tried to go to in the past few weeks commits and check if was something new in the project, but seems like Angular just dont reconize the component.

Does anyone knows how to fix it?

Thanks a lot!

SOLVED:

It was just uninstall the 2 packages:

npm uninstall ngx-dropzone-wrapper
npm uninstall dropzone

and them install again the packages in the newest version:

npm i dropzone
npm i ngx-dropzone-wrapper

Hello Nasco,

Im using these versions:
"dropzone": "^5.7.6"
"ngx-dropzone-wrapper": "^10.0.1"

Maybe if you update your dropzone-wrapper as I did, works!

Hi,
I too facing the same issue, it is working when updating the "ngx-dropzone-wrapper" version "^8.0.0" to "^10.0.0", but I need a permanent solution because I am using this in an Enterprise application, it should not happen again right? is there any other way to solve this issue permanently, why this was happen? @sconix pls help me

Thats what the package lock files are for, making certain that certain versions are installed. At least can not see any other reason than your installed package versions changing.

verison 11.0.0 has this issue for me.

Downgrading to 10.0.1 or using the other package above works for me

I have the same problem with version 7, 8 and 11. Only version 10 works for me.

Angular version 7.2.16

Still seeing this issue with Angular 14 with version 11

Added in .ts file in angular project:
import { DropzoneModule, DROPZONE_CONFIG, DropzoneConfigInterface, DropzoneComponent } from 'ngx-dropzone-wrapper';

Angular version: "@angular/core": "^5.2.4",

Can you give any idea how to fix this issue.
Thankyou in advance

[wratho]

this issue appears to still exist in the version 12? This seems like a pretty bad issue... and updates on an actual resolution?
seeing it on angular 14.2

[queejie]

Seeing this for the first time, with an upgrade to Angular 14.2.5. Is there a known workaround? Thank you.

SOLVED:

It was just uninstall the 2 packages:

npm uninstall ngx-dropzone-wrapper npm uninstall dropzone

and them install again the packages in the newest version:

npm i dropzone npm i ngx-dropzone-wrapper

This did not work.

This does indeed fix it, but it looks like they're getting out of sync. Would it be possible to incorporate this back into the main library? Thanks very much for this wrapper.
