dbt test fails because of space in source name

[Freia3]

After upgrading dbt from 0.20.1 to 0.21.0, dbt test fails because of spaces (and dot) present in the source name:

source.yml:

version: 2
sources:
- name: 'OMOP CDM v5.4'
  schema: omop
  tables:
  - name: cdm_source
    columns:
    - name: cdm_version_concept_id
      tests:
      - not_null

Error message after running dbt test:
16 of 184 ERROR source_not_null_OMOP CDM v5.4_cdm_source_cdm_version_concept_id [ERROR in 0.84s]
Database Error in test source_not_null_OMOP CDM v5.4_cdm_source_cdm_version_concept_id (sources/source.yml)
('42000', "[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Incorrect syntax near 'CDM'. (102) (SQLExecDirectW)")

I get the error in all dbt versions >=0.21.0

Is there any way to resolve this error without adjusting the source name?
