ERROR: Could not validate credentials to Confluent Cloud Schema Registry. Please troubleshoot

[NeilBumford]

Hi,

I'm getting the above error when trying to run the spring boot example.

I believe I have the Schema Registry set up and I've generated a schema registry key.

Here's my java.config:

`bootstrap.servers=pkc-l6wr6.europe-west2.gcp.confluent.cloud:9092
security.protocol=SASL_SSL
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username='[REMOVED KEY]' password='[REMOVED VALUE]';
sasl.mechanism=PLAIN

client.dns.lookup=use_all_dns_ips

session.timeout.ms=45000

acks=all

schema.registry.url=https://psrc-kk5gg.europe-west3.gcp.confluent.cloud
basic.auth.credentials.source=USER_INFO
schema.registry.basic.auth.user.info=[REMOVED KEY]:[REMOVED VALUE]`

I guess I've missed something?

@NeilBumford can you validate the credentials with something like the following (substitute your values):

curl -u <SR API KEY>:<SR API SECRET> https://<SR ENDPOINT>/subjects

[NeilBumford]

Hi,

It came back with:

[]

I guess that's a fail, then?

[ybyzek]

[] should be a pass and indicates no subjects are defined.

A fail would have resulted in some kind of more obvious auth error, e.g.

{"error_code":401,"message":"Unauthorized"}                                                                                                                       

[NeilBumford]

OK, so am I missing something?

[ybyzek]

@NeilBumford if this is for Springboot, the input configuration file should be of the syntax shown here: https://github.com/confluentinc/examples/blob/7.1.0-post/clients/docs/includes/configs/cloud/springboot-sr.config

[NeilBumford]

OK. Are you referring to java.config when you say "input configuration file" or should I have a springboot-sr.config file somewhere? I'm not very experienced with spring boot.

[ybyzek]

Whatever the file is that is input to the application, and yes, in your case it looks like you've named it java.config

[NeilBumford]

Just following the docs :)

Hmmm. Same error.

[NeilBumford]

There's this line above the error text:

curl: no URL specified!

[NeilBumford]

Don't know if this is relevant but this property in java_producer_consumer.delta isn't being written to:

schema.registry.basic.auth.user.info
