CAPTURE_CONTEXT INVALID Python

[MatiPendino2001]

Good afternoon, I am having trouble when I try to load the Microform.

1. details: undefined
2. informationLink: "https://www.cybersource.com/products/payment_security/secure_acceptance"
3. message: "You have not supplied a valid capture context."
4. name: "MicroformError"
5. reason: "CAPTURE_CONTEXT_INVALID"
6. [[Prototype]]: Error

That is the error I am receiving through the console. And this is an example of a captureContext I send:

1. {e: 'AQAB', kid: '08uZyNKNM7UCrMaEYEoTw3bvIVEGmLCw', kty: 'RSA', n: 'o_7iUSNypFkuFbrkTz3j-RopVy5YbemWXcdD_os29XLLLRDJtR…ulGSH4UNLTgX1Ug7jKThGAgp2xs3hoSW3tHAuM6dw6Li9fwBw', use: 'enc'}
1. e: "AQAB"
2. kid: "08uZyNKNM7UCrMaEYEoTw3bvIVEGmLCw"
3. kty: "RSA"
4. n: "o_7iUSNypFkuFbrkTz3j-RopVy5YbemWXcdD_os29XLLLRDJtRKoiFahBzplGBhl2yQNYHVkT7ChOYIySFS-WANfqApOoeKB1mv_JodgsQr3CxMMGq-A9XD_hkadM1Yz0w3fLCNsLREyodZtoalvrCOrGVIeH3mklglmN1YXG6DjPFLOeBKt0c4Kfq3jAcsNrGvevf8Tnhd3acQesUSDbZ3OCBLx4R5s_ETeEi7IGekIP91gXh80DWvCNm7L4oOSI4GCXFCZuST78nnNzcuVe36FoT1vXwTzvUCZpulGSH4UNLTgX1Ug7jKThGAgp2xs3hoSW3tHAuM6dw6Li9fwBw"
5. use: "enc"

I would really appreciate if anyone could help me with this, because I have followed all the tutorials, but I cannot implement the CyberSource Microform.
