Hi all, I am a developer of a LTI tool provider. when i try to use LTI1.3 and deeplink to create a ltirescourcelink type, it have some error.

Here you can see the log
Error ID #49648401432981305023774701209091750179835750405510267506.0
Error processing deep linking return

it just mention the jwt is invalid, but i have no idea about it, so could anybody can help me to check it?

and the jwt looks like this:

{
"alg": "RS256",
"kid": "faba9c42-7e4a-4c67-9fd6-b8592f491275",
"typ": "JWT"
