Syntax of insert query of Relation

I am trying to load data to the schema by Python client but I am facing a Syntex error in one of the relationship tempelate.

below is the error:

TypeDBClientException: [TQL03] TypeQL Error: There is a syntax error at line 1:
match $histology isa cancer, has cancer-id “CA-TCGA-4C-A93U”; $involve isa sample, has sample-id “TCGA-4C-A93U-01”;insert $neoplasm(histology: $histology, involve: $involve) isa neoplasm;$neoplasm has person-neoplasm-statusTUMOR FREE;$neoplasm has neoplasm-histology-typeThyroid Papillary Carcinoma - Classical/usual;$neoplasm has neoadjuvant-therapy-type-administered-prior-to-resection-textNo;
^
mismatched input ‘insert’ expecting {‘;’, ‘,’}

Could you try wrapping the attribute values in quotes?
I think the space in one of them is what triggered the syntax error.

match $histology isa cancer, has cancer-id “CA-TCGA-4C-A93U”;
 $involve isa sample, has sample-id “TCGA-4C-A93U-01”;
 insert $neoplasm(histology: $histology, involve: $involve) isa neoplasm;
 $neoplasm has person-neoplasm-status "TUMOR FREE";
 $neoplasm has neoplasm-histology-type "Thyroid Papillary Carcinoma - Classical/usual";
 $neoplasm has neoadjuvant-therapy-type-administered-prior-to-resection-text "No";
