got "[ERROR] DVSA backend does not work properly. Try to delete cache and re-login."

[Luca Di Domenico]

After deploy the application, I created a new user and logged in. After log in, the application shows a popup with the error message: "[ERROR] DVSA backend does not work properly. Try to delete cache and re-login."

I have investigated and this happens because the POST request to https://6u6eaiz6kk.execute-api.us-east-1.amazonaws.com/user/order return a 500 status code error, with the following response headers:

x-amzn-errortype: InternalServerErrorException
x-cache: Error from cloudfront

By examining the logs, it is caused by some nodejs missing dependencies. Has any other got this error? How to fix the missing dependencies error?

[Luca Di Domenico]

Yes, I'm using master.

Can you please paste the function's logs from CloudWatch logs?

Another thing is that i had to change the command:

webpack -p --env production --mode production

inside client/package.json to

webpack -p --mode production

because the command npm run-script client:build does not work in my case otherwhise.

can you please re-try now

I know its quite late. The problem was that the node-serialize was not included in the ORDER-MANGER package.
I've updated the version. you can take a look now.
