Gradebook Issue: lis_result_sourcedid passing as "{"

Gradebook Issue: lis_result_sourcedid passing as "{"

When students are launching into our tool the value of lis_result_sourcedid is being passed as "{". For this reason, when we attempt to post a grade the call fails. I have search all over and have not been able to figure out the cause of this. I have seen this across clients so it does not seem to be specific to a single client of ours.

Any help would be much appreciated.

Also this is an LTI 1.0/1.1 tool.

Thanks!

Hi Jason,

If the launch happens over 1.1 like you say, the value Moodle sends for lis_result_sourcedid will be a JSON string, which can then be saved by tools and sent back during grade sync. That '{' is only the first character. I'd suggest troubleshooting the launch and seeing why the rest of the data isn't present in that field.

Cheers,
Jake
