Self-Hosted Canvas LMS and Zoom LTI integration issue

Hello,

I have encountered the following problem when integrating Zoom into the Canvas platform. I was wondering if any of you have encountered something similar.

I am using Open source Canvas LMS and I have a paid Zoom Pro plan for one person. I have tried the integration with Zoom LTI Pro version 1.3.

I have tried several times to retry the integration following Zoom's instructions but I have not been able to remove the error.

Error code in Canvas:  500 - v=2.0;clid=aw1;rid=INT_fe763ae657fad2d7

Thank you in advance for your help.
