TypeError: Cannot read property 'substr' of undefined at stripTrailingSlash about client-js

[vlad-ignatov]

Sorry for the late reply. This should be fixed in [email protected]. If the launch URL is not loaded properly the launch will fail, but instead of showing such useless errors, there will be a warning in the console:

@dwilhel1 Was this fixed?

I am facing the same. Any solution yet?

[kperveen]

@bhupesh-sf It worked for me by putting a / at the end of launch url.

[bhupesh-sf]

This is the line being called

var server = urlParam("iss") || urlParam("fhirServiceUrl");

And inside urlParam() function

var query = location.search.substr(1);

And query is always empty so it is returning undefined as location.search has nothing.

@kperveen When I put / at the end of URL it gives 404

Ran into this issue when following the cerner tutorial :/ https://engineering.cerner.com/smart-on-fhir-tutorial/#app-launch because I tried to launch before running the app, as described in https://engineering.cerner.com/smart-on-fhir-tutorial/#test-your-app

I too am having this problem

Many thanks @vlad-ignatov!
