CloudPageURL is not working in SMS using Journey Builder

Question

I've found that the RedirectTo(CloudPagesURL) not working when the SMS is sent from Journey Builder. The link is working fine when testing in MobileConnect. Below is the ampscript I am using in the SMS.

%%[
SET @link1 = CloudPagesURL(1657,'Id','1234567890','option','1')
SET @link2 = RedirectTo(CloudPagesURL(1657,'Id','1234567890','option','2'))
]%%

Link1: %%=v(@link1)=%%%%=char(10,1)=%%
Link2: %%=v(@link2)=%%    

Below are the links generated.

Link1: https://pub.s7.exacttarget.com/0le55wmcyak?qs=e060acce0a7fb7a588df2e22b3bd7db7bd5a2e8bfb704548acd920295094828d18b0efa4f40a1c53045dcf8c8ef725c3

Link2: https://pub.s7.exacttarget.com/0le55wmcyak?qs=e060acce0a7fb7a588df2e22b3bd7db7bd5a2e8bfb704548acd920295094828d18b0efa4f40a1c535edbbe8a5f41a119

There's no need to wrap the CloudPagesURL function in a RedirectTo.

The CloudPage URL already includes all of the encrypted parameters in the send context.

%%[

SET @link1 = CloudPagesURL(1657,'Id','1234567890','option','1')
SET @link2 = CloudPagesURL(1657,'Id','1234567890','option','2')

]%%
Link1: %%=v(@link1)=%%
Link2: %%=v(@link2)=%%   

Not sure why you'd need the %%=char(10,1)=%% part at the end of the URL. That may be causing an issue.

Be sure and initialize your variables in the page:

%%[

var @id, @option
SET @Id = RequestParameter("Id")
SET @option = RequestParameter("option")

]%%
Id: %%=v(@Id)=%%
<br>Option: %%=v(@option)=%%

If it still doesn't work with these changes, then I suspect there's another issue in your CloudPage scripting.

If you just sending the SMS to the records who are not in the All Subscribers data then the personalised Cloud Page URL doesn't work.

All we need to do is create an automation to add the records to All Subscribers data. Once it is done, the personalised links using CloudPageURL will start working.
