Access token URL
Access token URL
I've created a platform (https://lti-ri.imsglobal.org/platforms/1339) to test my tool and getting stuck at the point where i need to retrieve an access token
When calling the access token url with the request below I get a 500 error with a 'Neither PUB key nor PRIV key: nested asn1 error' and I'm kind of at a loss what the problem is. Could you point me in the right direction?
OpenSSL::PKey::RSAError in AccessTokensController#create
Neither PUB key nor PRIV key: nested asn1 error
Extracted source (around line #55):
# we don't have the private key, so read public key directly
def openssl_tool_public_key
OpenSSL::PKey::RSA.new(tool_public_key)
end
end

I tested it with this platform https://lti-ri.imsglobal.org/platforms/1351/contexts connected to this tool https://lti-ri.imsglobal.org/lti/tools/1353
When i launch a deeplink flow from here: https://lti-ri.imsglobal.org/platforms/1351/contexts. I get the same error..
That helps - it looks like
That helps - it looks like your private key (tool) isn't in correct format (pem)- it should looks exactly like https://lti-ri.imsglobal.org/keygen/index including:
A good first step is to get it working with LTI RI Tool (so you can be sure it's working and the problem isn't with your local tool). I picked a random one that looks correct also, as an example: https://lti-ri.imsglobal.org/lti/tools/1352/edit
Thanks
Thanks it was al in the formatting of the key in the platform configuration..
Np at all, glad to help :)
