Google Storage setup: JSON parse exception

[Sean_Hagen]

Trying to get Google Storage set up for assets, and when nuxeo starts this is the error message I get:

Caused by: org.nuxeo.ecm.core.api.NuxeoException: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('/' (code 47)): maybe a (non-standard) comment? (not recognized as one since Feature 'ALLOW_COMMENTS' not enabled for parser)

The error seems to have something to do with the "\n" in the private_key value of the Google Service Account JSON key, which I don't think I should remove. Has anybody run into this problem and know how to fix it?

[Gregory_Carlin]

Hello, I've faced some issues related to the JSON structure. It should look like (data anonymized obviously, but you'll get the idea):

nuxeo.gcp.credentials={"type":"service_account","project_id":"my-super-project","private_key_id":"1234","private_key":"-----BEGIN PRIVATE KEY-----\\nXXXX/\\nXXXX

Does the JSON have to be put directly into the config file like that? I thought that nuxeo.gcp.credentials was supposed to point to the file that contains the JSON.

[Robert_Smith]

I'm experiencing a similar issue. I have to enter the JSON string in nuxeo.conf at nuxeo.gcp.credentials config parameter. Otherwise, I get the error list above. The key piece to getting mine to connect was escaping the \n with \n and adding a \r right before the 'END PRIVATE KEY' (/r\n-----END PRIVATE KEY-----).
