Subsequent Events [Abstract]
Subsequent Events	21. SUBSEQUENT EVENTS On February 15, 2023, the Company effected a 20:1 reverse stock split of its common stock in order to regain compliance with Nasdaq's continued listing requirements. All share and per share amounts, and exercise prices of stock options, warrants, and pre-funded warrants, if applicable, in the consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to this reverse stock split. On March 16, 2023, the Company received notice from The Nasdaq Stock Market LLC indicating that the Company had regained compliance with the minimum bid price requirement under Nasdaq Rule 5550(a)(2). In early March 2023, the Company received notices of certain alleged defaults and reservations of rights from Oaktree. The alleged defaults relate to (i) the Company exceeding the $10.0 million threshold for incurring additional indebtedness by having accounts payable owed to counterparties overdue by more than 90 days, (ii) the Company’s obligation to provide notice to Oaktree related to the foregoing, and (iii) the Company’s obligation to provide notice to Oaktree regarding the recent reverse stock split. Upon the occurrence of an Event of Default, Oaktree has the right to accelerate all amounts outstanding under the Senior Credit Agreement, in addition to other remedies available to it as a secured creditor. If Oaktree accelerates the maturity of the indebtedness under the Senior Credit Agreement, the Company does not have sufficient capital available to pay the amounts due on a timely basis, if at all, and there is no guarantee that it would be able to repay, refinance or restructure the payments due under the Senior Credit Agreement. In addition, an Event of Default under the Senior Credit Agreement may trigger cross-default under other agreements of the Company. The Company responded to Oaktree, including grounds upon which the Company disputes each of the alleged defaults. The Company has not reached a mutual agreement with Oaktree on this matter, and given the Company is in receipt of the notices of default and reservation of rights, which could result in payment to Oaktree on demand, the amounts due and outstanding to Oaktree are presented as a current obligation of the Company.
