Adding Bitbucket Repository connection fails with 500

[AlexanderLangguth]

Environment

self-hosted (https://develop.sentry.dev/self-hosted/)

Steps to Reproduce

1. Open the Settings -> Orgnanization -> Repositories section
2. Next to "Bitbucket", click on "Install Config"
3. Accept the OAuth in popup window.

Expected Result

The bitbucket repository connection is added to sentry.

Actual Result

The popup window shows my "Managed installed apps" page in bitbucket, and the URL has these parameters on it:
?error=server_error&error_description=The+app+failed+to+be+installed%3A+Error+calling+installed+at+URL+https%3A%2F%2Fself-hosted-sentry-domain.com%2Fextensions%2Fbitbucket%2Finstalled%2F%3A+500+Server+Error%3A+Internal+Server+Error+for+url%3A+https%3A%2F%2Fself-hosted-sentry-domain.com%2Fextensions%2Fbitbucket%2Finstalled%2F&principal=our-principal

(I replaced our domain with self-hosted-sentry-domain.com and our principal with our-principal.

When i check the logs of the docker containers i see these:

From postgres-1:

I guess the external_id field is too long?

The original with our own domain is 103 characters long. But even up to the / behind the uuid it is already 64 characters.
