Exception Creating Index

I am calling:

await mPinecone.CreateIndex(indexName, dim, metric);

where indexName is "index1", dim is 1536, and metric is Pinecone.Metric.Cosine

and getting this exception:
CreateIndex request has failed. Code: BadRequest. Message: The index exceeds the project quota of 1 pods by 1 pods. Upgrade your account or change the project settings to increase the quota.

I thought that if I do not specify anything it uses p1.x1 by default for free account…
Am I wrong? If not why the exception?

Only one Index can be created with a free account.
I think the error is occurring when trying to create a second Index.
